1.14/1.15 FabricMC registry sync packet support and/or handshake #168
Description
Fabric servers usually have a registry-sync plugin to send a packet to synchronize registry identifiers: https://github.com/FabricMC/fabric/tree/master/fabric-registry-sync-v0/src/main/java/net/fabricmc/fabric
According to @asiekierka they are also working on a handshake. Should see about supporting at least the registry sync, and/or the full handshake once implemented. For comparison, Forge 1.7.10-1.12.2 has the RegistryData and ModIdData packets: https://github.com/iceiix/stevenarella/blob/master/src/protocol/forge.rs#L152
Not sure if this would solve #155 FabricMC unrecognized recipe type

To get familiar with related registry ID changes, may want to first fix and finish #145 Forge 1.13.2.
