Make ViaFabric universally compatible with 1.14 and up

[Kichura]

Since people tend to complain about specific minecraft versions being absent from supported versions list, We should probably figure out on how to make this mod universally compatible without having to make duplicate code for each version.

Legacy versions (this case: 1.13.2 and under) aren't officially listed by normal fabric installer and therefore isn't high priority.

Could use some preprocessor like Unimined
