Adding new supported display ED052TC4 1280x780

[martinberlin]

Adding this nice and cheap display (17€ in Aliexpress)
Similar to Lilygo EPD47 but slightly bigger and more resolution. Grays work but only 9 scales or so, probably needs better gray matrix. I will stop calling it waveforms since it's actually a 2 bit data stream, with transitions from Gray1 to Gray2 :D
More grays but still not perfect using the Lilygo ED0457TC2 double passes waveform file.

In this update I'm also adding some fixes to my www-image example:

• Moving display into settings.h so you don't have to touch the main file
• Updating logging related errors (The usual this is not an (int) or not a large int)

Ok I'm hitting here some strange validations from the auto checks CI:

/opt/esp/tools/xtensa-esp-elf/esp-13.2.0_20240530/xtensa-esp-elf/bin/../lib/gcc/xtensa-esp-elf/13.2.0/../../../../xtensa-esp-elf/bin/ld: esp-idf/epdiy/libepdiy.a(epd_board_v7.c.obj): in function epd_board_deinit': /app/vroland/epdiy/src/board/epd_board_v7.c:148:(.text.epd_board_deinit+0x3): undefined reference to epd_lcd_deinit'

I don't really see in VSCODE epd_lcd_deinit exits and it's referenced. It builds and flashes without any problem

Not sure why the linker problem occurs, but could we split up adding the display and updating the examples into separate PRs? Maybe then the issue gets easier to debug as well.

[martinberlin]

Sure later will do that.
@vroland what do you think is the best strategy to work out the mirroring X issue on this displays?
Is the best to make an ifdef or add it as a displays.c property?
