[LookUpAnything] Spacecore skills support
Added support through the spacecore API so look up anything will display custom skills.
It requires this pull request from spacecore to function fully: https://github.com/spacechase0/StardewValleyMods/pull/458
So only accept this PR (or only push the update) once that one goes through.
Also ignore how luck skill is going a little bit over the line. That's due to how you can get negative exp in the luck skill and is not related to this PR.
Thanks! I marked this as draft temporarily until the SpaceCore PR is merged and released.
Merged into develop for the upcoming Lookup Anything 1.46.0. Thanks for the help!
