Add `libsqlite3-sys` crate to avoid sqlite3 missmatching version.
From [https://lib.rs/crates/libsqlite3-sys](https://lib.rs/crates/libsqlite3-sys)
> If you use the bundled feature, libsqlite3-sys will use the cc crate to compile SQLite from source and link against that. This source is embedded in the libsqlite3-sys crate and is currently SQLite 3.30.1 (as of rusqlite 0.21.0 / libsqlite3-sys 0.17.0). This is probably the simplest solution to any build problems.
Remove sqlite OS packages dependencies for build.
Also, we fix a format error to allow CI tests to pass again.
Implements #12, TOTP. This adds support for TOTP to the api and server, with server side token generation, authentication and the correct URI for encoding into QR codes for client token addition. Some extra measures have been taken such as in the stepped auth to always notify on the success or failure of the TOTP first (regardless of order) to prevent PW bruteforce attacks.
Implements #122 password import. This adds most of the server core framework to allow password imports from other sources, with new types easily able to be added in credential.rs.
