.elytra file format for world compression

[TommyAlmeida]

Description In order to be effective to save world data or backup it we decided that we are gonna create a .elytra file format instead of using the old .region file format.

Why? Region files add unecessary data to the files that takes a lot of bytes filling up the space very quickly and difficulting operations in bulk.

Must use zstd instead of the zlib
