API License Change

[florianreuth]

For ViaFabricPlus 5.0.0, I'd like to relicense the API submodule from GPL v3 to the MIT License to make it easier for other projects to use and integrate.

If you've contributed to the API submodule, please reply to this issue with something like:

I consent to relicensing all of my contributions to the ViaFabricPlus API submodule from GPL v3 to the MIT License.
