[TriEmbed] Micropython and LVGL on ESP32?

Managed to get some progress by checking out the v1.14 merge of 
lv_micropython instead of the head of master.

Have BLE and the TFT/touchscreen working with micropython though BLE is 
somewhat unreliable (operations sometimes timeout) compared to using 
plain micropython without lvgl bindings.  Not sure if there is a 
correlation or not.

Certainly interesting to do this in python instead of C but not sure it 
is quite baked yet.
