Stop ProtocolSupport from crying

If I ever tried to either cast or use FloodgatePlayer as a return type
when Floodgate was not installed in the server, I got this error:

[19:37:46 ERROR]: [FastLogin] Plugin FastLogin v1.11-SNAPSHOT-744264d has failed to
register events for class
com.github.games647.fastlogin.bukkit.listener.protocolsupport.ProtocolSupportListener
because org/geysermc/floodgate/api/player/FloodgatePlayer does not exist.

ProtocolLib doen't have this problem.
