0.9.1 - Fix #266 (the 'esp32 loses BLE pairing' bug). Other benefits:
- 4x faster
- substantially lower RAM and FLASH consumption (which makes plenty of IRAM space to leave wifi always enabled)
- Eventually will allow the same BLE implementation on NRF52 and ESP32 targets - because NimBLE can run on both platforms
- BLE 'handles' are assigned in a stable fashion, so eventually (after widely deployed) the nasty "force service refresh" hack needed on Android clients can be removed.
NOTE You will need to re-pair once 😄 after installing this new load (because it is keeping different device signing data than the old Bluedroid based implementation)
