Log date formatter changed with the latest build

[frebib]

Thanks for updating/fixing the logging in the latest build.
The format changed for me, though

Our Bungeecord instances uses a different date format specified at runtime:
spritsail/bungeecord@b79e9f8
The ConciseFormatter that was used before reads that variable, and defaults to HH:mm:ss:
https://github.com/SpigotMC/BungeeCord/blob/master/log/src/main/java/net/md_5/bungee/log/ConciseFormatter.java#L17

Could this override be re-added, please

Better still, it looks like the ConciseFormatter can still be used, but using one of the Lombok constructors, as upstream does here: SpigotMC/BungeeCord@bf673c5#diff-bb12962309e5cb9baadb0b934fd0f074R29

The empty constructor is Protected, which is why it throws nasty warnings
