Add AMS 2 Pro filament drying support#440

The AMS 2 Pro with its filament drying, has been a fantastic addition to our print farm. It would be greatly appreciated if SimplyPrint could support the filament drying feature as well.
Some ideas:

• Automatically drying filament when humidity reaches a certain level
• Drying filament when the printer is idle
  Etc.

Additionally, showing the current humidity level in SimplyPrint would be huge. These filament drying settings could potentially be applied to other filament dryers in the future aswell.

Thank you for your time.
