* 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.

- Wifi connection progress is now visible on the TFT
- passthrough serial logging from the C6 to the S3 terminal for easier debugging
- no checks on force_flash and APtag-firmware version when C6 is used
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).
