MCA Wandering trader Compat

Changelog — 1.1.0

New: choose the adventurers' companion animals

• New config option companionMobs in mcawtcompat-common.toml. It lists the animals adventurers can arrive with. The default is still llama, horse, donkey, cat and wolf, so nothing changes unless you edit it.
• Modded mobs work too, e.g. iceandfire:fire_dragon or alexscaves:candicorn.
• Leave the list empty and adventurers arrive alone.
• IDs that don't exist and things that can't be leashed (boats, armor stands...) are skipped with one warning in the log, never a crash.

New: /wtconf command (ops only)

• /wtconf companions list: shows the current companion list.
• /wtconf companions add <entity>: autocompletes like /summon, so you can't type an ID that doesn't exist.
• /wtconf companions remove <entity>: autocompletes from your list.
• /wtconf companions reset: back to the original five.
• /wtconf companions test: spawns an adventurer with companions right where you're standing.

Changes made with the command apply straight away and are saved to the config file, so there's no restart and no file editing needed.

Thanks to MythicalMontie for the suggestion!
