Timing issues in display_frame function: epd1in54 and epd2in9 were both missing a necessary wait_until_idle call at the end of their display_frame function which sometimes caused invalid/ignored commands/inputs afterwards
Some CI Targets were not tested correctly before

"cargo fix --edition" for the library
Use cargo fix edition-idioms and remove the internal renaming from embedded_hal to hal
moved width, height and default_background_color directly to epd4in2 module
