Mark Loot Sheet NPC 5E as dependency so that the Module Management screen will track it

[TheRealIceCracker]

Is your feature request related to a problem? Please describe.
Loot Sheet NPC 5E isn't marked as a dependency, so the Module Management screen won't notify you if you don't have that installed as well. This renders this module non-functional with no clear in-app indication why.

Describe the solution you'd like
Loot Sheet NPC 5E marked as a dependency such that the Module Management screen will notify you if you don't have that installed or enabled.

Describe alternatives you've considered
At the end of the day I figured it out just by reading the module description again, but most other modules have this functionality and I assume (please don't crucify me if it's not) that it's pretty low lift.

Additional context

The whole thing needs a rewrite, and might not rely on any loot sheet when its done. Closing this for now
