Asset Resaver Editor Script

[FlorianGlawogger]

Describe the issue
We have many older scenes or prefabs in Maroon, when changing only a tiny part of the prefab/scene, there are changes all over the file, as the Unity version has changed and some serialization parts are now different. This leads to confusion in Pull Requests, as there are easily 1000+ lines of changes when you actually only want to change one thing about an asset.

Potential solution:
A potential solution could be to write an Editor script, that opens and resaves all prefabs and scenes.
