chore(patch): Removing SQLx package

[Jacobbrewer1]

Describe your changes

If users are using the sqlx package for their databases, then they can call the WithDB opt and pass in the DB object that is part of the sqlx struct.

sqlxDb := sqlx.Open("mysql", "some-conn-str")
opt := patcher.WithDB(sqlxDb.DB)

This closes #51
