IModLanguageProvider#loadMod signature is really weird

[Technici4n]

The signature is:

    interface IModLanguageLoader {
        <T> T loadMod(IModInfo info, ModFileScanData modFileScanResults, ModuleLayer layer);
    }

however T should actually be ModContainer, which is NOT part of the SPI. A bit tricky to handle I think.
