Split sqlite db module of pmrmodel to own package

- Given how sqlx 0.9.0 is still not released yet which may permit a
  crate to support multiple database backends, and that we will need to
  provide a pgsql backend sooner rather than later, just have the sqlite
  part in a separate crate.
- This only provides the new crate, the plumbing to hook this up as a
  consistent API will be provided later.
