[BlockInfo] Increase the amount of blocks and biomes that can be registered.

[granny]

Currently there is a limit of 1023 registered blocks and 1023 registered biomes. Find a way to increase that limit for blocks (Mojang currently has up to 1096 blocks and 65 biomes).

Three ways this could go:

1. Just go ahead and lower the limit for biomes and increase the limit for blocks.
2. Change the packed integer into a packed long.
3. Dynamically adjust the limit for blocks and biomes, with priority for blocks.

All three possible solutions would require making changes to the pl3xmap file protocol, which means changing how it functions in the webmap. An announcement in the discord will need to be made to let users know of this change for those who have read-only set to true in their config.
