Ensure Numeric Values in Slots for HassStartTimer

[mitrokun]

Some ASR systems return numbers as words. The project has a library (unicode-rbnf) that correctly processes such values. This allows the timer to start correctly on the satellite, but the intent processing is interrupted by an error, the response logic cannot be processed correctly, since slots contain words instead of numbers.
It is entirely possible to complicate the response code to handle all cases and perform the replacement using a dictionary. However, I would like to get a simpler solution. It is enough to use the value that is passed to the satellite.
