Support for RTS shutters

[Programmierfreund]

@nikkow Thank you for the successful V3 betas. The support of the new local API works wonderfully for me. However, I still have RTS shutters, so for me only the commands "open" and "close" are relevant. I have now read out via the Tahoma Read Node once the possible commands of a RTS shutter. These are:
stop, test, open, close, identify, up, down, my, openConfiguration and rest (see attached file for a detailed log).

I really need the "my" position for controlling my shutters and I just added the command once in the tahoma.ts file now:

interface ITahomaControlInstructions {
command: 'open' | 'close' | 'rotation' | 'stop' | 'my' | 'setClosure';
....

function generateInstructionsFromPayload(
.......
case 'my':
return {
command: 'my',
labels: {
done: Positioned,
progress: Positioning...,
},
};
......

I then followed up with these changes manually (because I did not want to compile the ts file) in the tasmota.js by overwriting the installed file and the my command now works great with my RTS shutters.

@nikkow Could you please add the "my command" in the main branch of your project?
