T-Watch 2020 compilation issues

[wizche]

I'm trying to build this for the 2020 model and noticed that the define is LILYGO_TWATCH_2020_V1. According to other example sketches it should be LILYGO_WATCH_2020_V1.

Despite that I still get a gazillions compilation issues 😄 Looks like some LVGL API changes, currently (according to TTGO doc) its using v7.0 but the AWatch project seems to use v6 API. Maybe I need to use an older version of the TWatch Library....

Btw... very cool project!
