AdafruitSensorMeasurement does not allow a sequence number of 0 in constructor

[kevinjwalters]

The constructor for AdafruitSensorMeasurement conditionally sets sequence_number based on testing the variable, 0 will evaluate to False causing no setting of the sequence_number.

Adafruit_CircuitPython_BLE_BroadcastNet/adafruit_ble_broadcastnet.py

Lines 156 to 157 in 81aee22

	if sequence_number:
	self.sequence_number = sequence_number

Perhaps this was intended to be is not None?

The broadcast function in the same file does not use the construtor's arguments to set the sequence_number.

This is just from inspection, I've not executed the code...
