Non deterministic encryption VFS

[alvarolm]

Since I could not find any, decided to make an implementation using chacha20 poly1305

https://github.com/alvarolm/go-sqlite3-xchacha

had to accommodate 20 bytes per page (nonce+mac), in the db file used reserved bytes, and in the aux files offset translation
its not pretty but it works

any feedback is appreciated

Cool. 😎

Nothing immediately jumps out. I hope you had fun building it!

https://utelle.github.io/SQLite3MultipleCiphers/ is the impl I know that does this as a VFS. It sounded complicated, so I decided to go with something radically different, easier (for me) to reason about.
