v1.2

Major changes to default behavior:
- If time is not specified, whatever mode is selected will run until the vacuum gets low on battery. Then it will go home.
- If a time is specified, vacuum will run until the end of elapsed time then it will stop in place.
Addition of a mode flag:
- -m quiet: Automatic direction, low suction
- -m default: Automatic direction, medium suction
- -m max: Automatic direction, maximum suction
- -m edge: Stick to the edges of the room
- -m spot: "Spot clean" - goes in goes in a spiral from one point
Addition of a status flag:
- -s or --status will connect to robovac and print status.
Improve tuya logs and callbacks by associating status names with their values.
- whereas before, status indicators such as "power" and "work mode" were reported as numerical keys, the keys are now just called "power" and "work mode".
add a return to base flag
- --return or -r: when combined with --time or -t, will instruct robovac to return to base after time has elapsed. (default is to pause in place when time elapses).
- This is semantically different from -b or --home because it only impacts a timed job.
