Possible type bugs for wire types in AdafruitSensorMeasurement

Comparing https://github.com/adafruit/Adafruit_CircuitPython_BLE_BroadcastNet/blob/c6328d5c7edf8a99ff719c3b1798cb4111bab397/adafruit_ble_broadcastnet.py#L129 with https://circuitpython.readthedocs.io/en/5.0.x/docs/design_guide.html#sensor-properties-and-units there are a few type mismatches:

- `color` - `f` vs int (32bit is used in `AdafruitColor()`)
- `duty_cycle` - `f` vs int (16bit int?)
- `frequency` - `f` vs int
- `value` - `f` vs a "union" of int (16 bit) /bool

Start at adafruit_ble_broadcastnet.py around line 129 and compare the wire types for color, duty_cycle, frequency, and value with the CircuitPython sensor properties and units documentation linked in the issue. Confirm the documented and encoded types agree for all four fields; done means the mismatches are resolved and the relevant values remain compatible with the broadcast format.
