Database importing

[ReCore-sys]

This PR adds the functionality necessary for importing chunks into the database

Description

Using the anvil parser added in #100 this PR adds functionality for reading chunks from anvil files and storing them in the database. It also adds methods for storing, loading and deleting chunks. Additionally it also adds the ability to serialize chunk data into an in-memory struct, using the NBT parser added in #53. GZIP and Redb have been selected as the default compression scheme and database backend.
This PR also changes the format of the config system, so not pulling the changes will result in merge conflicts or compilation issues.
The database functionality is in no way complete, but should suffice for now to allow for chunk sending.

Motivation and Context

Chunk importing is vital for any kind of interactivity without chunk generation implemented.
Issue: #95

How has this been tested?

This has been tested multiple times manually but would be very difficult to create unit tests for and would not play nicely with CI so they have not been included. Tests for data validity have not been included since it would be impossible to test without chunk sending (#70) implemented.
