Track when filament dried

[SConaway]

Hi there,

I'm looking to integrate tracking of when spools are dried into my Spoolman workflow. Is this a feature that you'd be willing to include in the main application? I'd be willing to prototype/develop this feature on both the server and client, but wanted to check first. Alternatively, this could be something that uses the inbuilt REST APIs and just uses Spoolman as the datastore. Let me know what you think, thanks!

@Donkie is this something you'd be open to me integrating directly in Spoolman?

See #711 for a draft of this functionality
