This patch enables having a top-level `sqlx-data.json` file within a
workspace.
It does this by using a full clean / check instead of `cargo rustc`
which fails on a workspace.
A `--merged` flag is introduced to switch to the workspace behavior
Fixes#353.

- adds a -r flag whihc will create a reversible migration
- add revert subcommand, which reverts the last migration
- add --dry-run flag to migration run command, which list the migrations that will be applied
- updates add migration to check if all migration are of same type, i.e cannot mix and match reversible and simple migrations
The reset command is the equivalent of `sqlx db drop`, `sqlx db create`,
and `sqlx migrate run`. Unless the `-y` parameter is specified, it will
prompt confirmation before dropping the database.
