More displays, improved ui, unified ui (2)

Same as v1.2.0, but this time hopefully with a valid version number :)

• The codebase has been rewritten to be more responsive and ui elements to be scaled according to screen configuration. This allows porting CYD-Klipper to different screens with different sizes(!) (#17)
  • It is still an early implementation. If you like CYD-Klipper to be ported to a different screen, please open an issue for it
  • Currently, an additional implementation is available for an ESP32-3248S035C
• A new stats screen is introdued to display print stats during a print. On this screen you can also modify fan speed, z offset, speed and flow. (#8, #23)
• Some characters, like & and ^ were inaccessible in the wifi password keyboard entry. This has now been resolved. (#19)
• Klipper IP can also now be a hostname (#27, #29, #33)
• Moonraker power devices can now be toggled via CYD-Klipper. Power devices are shown, if available, in the macros menu, in the printer error screen and the klipper connection attempt screen. (#20)
• The install website has been slightly overhauled
• The version of CYD-Klipper is now shown in the settings
