More meaningful charging state

[kifort]

Wrong packet ID is used for battery voltage at

MQTT-Roomba-ESP01/RoombaESP01_CONFIGURE.ino

Line 126 in 7ad7cd0

roomba.getSensors(21, tempBuf, 1);

Packet ID 21 is the Charging State
Packet ID 22 is the Voltage

It is only a variable naming issue, but the integer value of Packet ID 21 can be mapped to a more meaningful name based on the Code and Charging State mapping.

I agree with you! You can suggest a pullrequest to this code? I don’t think @thehookup can review its code
