1.16 server compatibility indicator fix

[kmecpp]

Server compatibility indicator is broken

This code in initialization will fix it:

ModLoadingContext.get().registerExtensionPoint(ExtensionPoint.DISPLAYTEST, () -> Pair.of(() -> FMLNetworkConstants.IGNORESERVERONLY, (a, b) -> true));

Code is from the Forge documentation: https://mcforge.readthedocs.io/en/latest/concepts/sides/#writing-one-sided-mods
