[REQUEST] Support for Tools (and Soundtracks)

[RowanSkie]

Is your feature request related to a problem? Please describe.
Something I noticed is the fact that Soundtracks and Tools don't appear, leading to me having to reorganize my Steam collection post-upgrade.

Describe the solution you'd like
A way to also sort Tools and Soundtracks via Depressurizer

Describe alternatives you've considered
I've needed this because I'm using steamgrid to mark if the app/game/item is a tool or something, and the fact that Depressurizer doesn't detect them is extra pain.

Additional context
None
