Add Lolin C3 Mini board

[Bre77]

I have successfully deployed this library onto a Lolin C3 Mini V1, so adding its board configuration.

Thanks for adding, LGTM overall

• could you add a base yml in the root of the project? like https://github.com/yoziru/esphome-tesla-ble/blob/main/tesla-ble-esp32-generic.yml (so you can make compile BOARD=lolin-c3 + import the yml in ESPHome dashboard)
• could you add it to CI so the builds work? see https://github.com/yoziru/esphome-tesla-ble/blob/6b865fe827cdb533c29ff189ac63195647cc6093/.github/workflows/ci.yml#L15

also works fine on "generic" C3, in my case C3 mini from Aliexpress:

esp32:
  board: esp32-c3-devkitm-1
  framework:
    type: esp-idf
    version: $espidf_version
    platform_version: $platformio_version
