* Fix filesystem mutex handling
This fixes the re-initialization of the filesystem mutex when the dyn storage
module is reinitialized. Using xSemaphoreCreateMutex would cause a memory leak
when the begin function is called multiple times and a semaphore leakage could
be caused by the re-initialization of the global fsMutex variable while the
semaphore is taken.
The fsMutex should not be taken while the logLine function is called as this
would cause a nested take of the fsMutex, which causes a deadlock.

* Add new AP hardware support OpenEPaperLink_ESP32-PoE-ISO_AP
This is based on Olimex ESP32-PoE-ISO
https://www.olimex.com/Products/IoT/ESP32/ESP32-POE-ISO/open-source-hardware
It has a SD Card slot that is used to store all filesystem data on SD.
Use the prepare_sdcard.sh script to copy all needed data to an empty
SD card that is formatted with FAT filesystem. The AP firmware will format
the SD if an unformatted or from formatted card is used. This can be used
to intially prepare an empty SD card for usage.
For tag communication a ESP32-C6-WROOM-1(U) is used with the following
connection scheme:
ESP32-PoE-ISO | ESP32-C6-WROOM-1
---------------+------------------
GPIO5 | EN
GPIO13 | GPIO9
GPIO36 | GPIO3
GPIO4 | GPIO2
GPIO33 | GPIO24
GPIO32 | GPIO25
| GPIO8 pullup 5.1k

* Workaround for IEEE802.15.4 modem stuck issue
The ESP32-C6 esp-idf based modem firmware can run into a case where it
does not receive data anymore from the tags. This can be detected when
it starts to print
"receive buffer full, drop the current frame"
and does not recover from that. In such a case a modem reset is triggered.

* Add Ethernet support
The ethernet support allows to make the network/internet connection
via LAN cable instead of WiFi. LAN is preferred, if a LAN cable is
connected and a valid IP configuration via DHCP can be obtained, WiFi
is switched off. If the LAN cable is disconnected, a fall back to
WiFi is done.
Use those defines in platform.ini for PHY settings:
ETHERNET_PHY_POWER: IO pin where the PHY can be switched of/on, can be
-1 if not used.
ETHERNET_CLK_MODE: PHY clock mode, see eth_clock_mode_t in ETH.h
ETHERNET_PHY_MDC: PHY MDC pin
ETHERNET_PHY_MDIO: PHY MDIO pin
ETHERNET_PHY_TYPE: PHY type, see eth_phy_type_t in ETH.h
Limitations:
- only DHCP is supported, no static IP configuration for LAN so far.
- If GPIO0 is used for one of the ETHERNET_CLK_MODE modes, then GPIO0
cannot be used to clear the WiFi configuration.

- added webinterface for tag flasher
- added tcp transport for communicating with tag flasher (OTG USB also still works)
- added content 'timestamp', makes use of preloaded images and buttons on the 2.9" M3
- webinterface is now aware of C6 and flasher capabilities
- AP can run without ieee801.15.4 radio (i.e. flasher only) by shorting FLASHER_AP_TXD and FLASHER_AP_RXD
- added tcp transport option to OEPL-Flasher.py (serial also still works)
- added new environment OpenEPaperLink_Mini_AP_v4
- lots of finetuning and bug fixes
- added short date format definition in language.json
- changed english date format to mm/dd
- added lightgrey (4)/darkgrey (5)/pink (6) colors in jsontemplate (uses pattern dither)

This one saves a lot of flash space.
Now, wifimanager is replaced with our own method for managing the wifi connections.
Also, the whole thing will run now even if there is no wifi. If wifi disappears, it automatically tries to reconnect in the background every few minutes.
Wifi settings now available at all times at /setup
If it cannot connect, an access point 'OpenEPaperLink' is created where you can set the wifi credentials (http://192.168.4.1/setup).
To be able to store more images and never worry about running
out of storage again we are adding support of SDCards.
We are faced with two options:
1) Remove the LittleFS code
2) Allow for both FSs but increase the app partition as we run
out of space.
We have opted for 2 for two reasons:
1) Unformated SDCards can be initialized from the littleFS
2) If the SDCard and the flasher share the same SPI pins
the SDCard needs to be completely disconnected so there needs
to be a FS in that rare case.
Performance wise the SDCard is not slowing the system down.
Writing the AP db with 70 APs takes 2.5 seconds, on the SD
only 800ms. This however is SD and setup depending.
By default the SDCard is expected on pins 18,19,23 however this
is configurable via preprocessor defines.
Globally we replace LittleFS with a new pointer to the currently
used FS allowing for hotswapping where the FS pointer is not saved.
One case which is therefore not working is the SPIFSEditor which
copies the FS interally.
