Missing state translations

[AverageMarcus]

I noticed this morning that sensor.tumble_dryer_program_phase initially has a value of 1 when starting a new run, shortly followed by it moving to Drying.

It looks as though the tumbledryer_program_phase translation is missing for 1 so not providing a human-friendly display value. I was too slow to check the official app to see what it calls that phase but I suspect it's something along the lines of "Starting".

I also noticed in this issue comment that there seems to be translations missing for other devices too. I'm wondering if it would be helpful to track the ones that are missing so people with those devices can contribute what the numbers relate to in the official app.

Additionally, I wonder if it would be useful to have a "fallback" value of "Unknown State" or something when a translation doesn't exist so that users aren't just presented with the confusing number?
