Figure out intended license

[JonnyOThan]

The readme file said MIT, but the .netkan files say CC-BY-NC-SA-4.0. Need to figure out which it is before the next release.

Noting for traceability as on Discord, the intended license is

• MIT for code and configs
• ARR for models, textures and other art assets.

KSPModStewards is granted a license to redistribute the assets on organization repos
