Megalodon: manage ARK servers over RCON from a web dashboard

Watches any number of ARK:SE servers (RCON for players and chat, the query
port for map, version and player cap), records joins, leaves, chat and an
audit trail, and keeps a player database across servers.

Control: save, broadcast, chat, whisper, kick, time of day, MOTD, wild dino
wipe, a raw console with history and macros, restarts with timed warnings and
a world save, optional start command and auto-start. Bans are kept by
Megalodon: timed, cluster-wide and re-enforced when the player returns.

Automation: schedules (every N or at times of day), Discord/ntfy/webhook
notifications, welcome message, chat word filter.

Access: viewer, moderator and admin roles, API tokens, Prometheus metrics.
cmd/fakeark simulates a server for trying it out.
