Work in progress. Does not work yet.
Some notes:
- This requires some changes to TinyGo, look at the espnet branch.
- The next step is probably defining all the functions in
g_wifi_osi_funcs (see espnet.c). Right now it hangs in
esp_wifi_init_internal, probably a NULL pointer dereference.
- This is only for the ESP32-C3. This will require some work to work
on other chips from Espressif.
