/*
- SQLite format specification:
- - Initially only replaces sectors/ and sectors2/
-
- If map.sqlite does not exist in the save dir
- or the block was not found in the database
- the map will try to load from sectors folder.
- In either case, map.sqlite will be created
- and all future saves will save there.

- Structure of map.sqlite:
- Tables:
- blocks
- (PK) INT pos
- BLOB data
