RFC2324 interface for TI9558X1DE

[osresearch]

Now that the coffee machines can be connected (#3), we need to build an RFC2324 compliant interface https://datatracker.ietf.org/doc/html/rfc2324

[CRTified]

As the TI9558X1DE can also supply hot water, I'd argue that RFC 7168 is more appropriate (building on RFC2324).

And without joking: Having some way to set profiles like water temperature and volume would be awesome, but I'd heavily suspect that it should not be in the scope of hcpy, but in the scope of whatever is used to interface with it in the long run (e.g. the MQTT client, or automation tools like home assistant).
