Adafruit-circuitpython-ble

Changes in how advertising was done in CircuitPython caused this to fail. This fixes the problem.

To use in CircuitPython, simply install the [Adafruit CircuitPython bundle](https://github.com/adafruit/Adafruit_CircuitPython_Bundle).

Read the [docs](http://circuitpython.readthedocs.io/projects/ble/en/latest/) for info on how to use it.

For use with CircuitPython 5.0.0-beta.0 or later.

- Add Apple Notification Service support and example.
- Fix iOS HID.
- Add Magic Light LED lightbulb support and example.
- `Add BLERadio.name` and `BLERadio.tx_power` properties.
- Include `BLERadio.name` in advertisement scan response

This release is not compatible with CircuitPython 4.1.0. For 4.1.0, use release [1.0.2](https://github.com/adafruit/Adafruit_CircuitPython_BLE/tree/1.0.2) of this library. Due to current limitations in our library bundle packaging, the 4.x library bundle will contain this release, not the [1.0.2](https://github.com/adafruit/Adafruit_CircuitPython_BLE/tree/1.0.2) release.

- Match `_bleio` changes in CircuitPython 5.0.0-beta.0.
- Define BLE services declaratively, so that they may be used either on the client or server side of the connection.
- Rework advertising packet construction.
- Update examples for new API, and add some new examples.
- Do a CircuitPython version check to ensure compatibility.

This pre-release is compatible with CircuitPython 5.0.0-alpha.2, .3, and .4, and .5. `bleio` has been renamed to `_bleio` and there are other changes for compatibility.

This pre-release is compatible with the upcoming CircuitPython 5.0.0-alpha.1 pre-release.

- Improve ble_demo_central.py example so it reconnects to any compatible peripheral after disconnect.
