When an SD Card is available it is the more interesing
metric in terms of space usage. We are therefore using
it here.

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.

Beyond around 20 APs the littleFs will no longer provide enough
space to add .pending files. The original .raw files are premarily
held to be able to send them to the web interface.
In those rare cases where this is not strictly needed we can
allow specific setups to auto-delete them.

The M5stack board offers three interesting features for use with
OpenEPaperLink:
- LCD
- SDCard slot
- Modules including a batters
Which means it can easily be used to walk around with an AP for testing
purposes.
The LCD is currely not used as the M5Stack library is so old that it collides
with newer versions of eTFT which we are importing already.

The original weemos D1 mini was one of the most popular
ESP8266 boards. To this day many designs are designed around its
formfactor.
The successor is the here added D1 mini 32. It brings the same
"core" header with 8 GPIO but also additional io.
We are adding a default config which is workable with the old
pinconfig as those are usually the only ones exposed on the
breakout boards.
- added Swedish å Å to Bahnschrift20 and 30
- option to turn dither on/off in 'static image'
- major overhaul of contentmanager.cpp, content is now generated from json template.
- fallback to 1bpp for 4.2" when no psram
- added 4.2" content layouts
- fixed small apconfig bug
- pause content generation for 60 seconds after crash, to prevent uncontrollable boot loop
- fonts re-rendered: added äöüßÄÖÜ.
- shuffled a bit with fonts to optimize disk usage
- ability to delete files during OTA
- prettify tagDB.json
- error handling in get_DB
- small cosmetic changes
* Due to new ability to delete files: After firmware update via OTA, please perform an OTA update of the filesystem again to perform the deletion of unneeded fonts.
* If updating via platform.io: don't forget to update the filesystem image.
