Adds support to apply migrations without versioning (#291)

README.md

@@ -30,6 +30,7 @@ Goose supports [embedding SQL migrations](#embedded-sql-migrations), which means
     - goose pkg doesn't have any vendor dependencies anymore
 - We use timestamped migrations by default but recommend a hybrid approach of using timestamps in the development process and sequential versions in production.
 - Supports missing (out-of-order) migrations with the `-allow-missing` flag, or if using as a library supply the functional option `goose.WithAllowMissing()` to Up, UpTo or UpByOne.
+- Supports applying ad-hoc migrations without tracking them in the schema table. Useful for seeding a database after migrations have been applied. Use `-no-versioning` flag or the functional option `goose.WithNoVersioning()`.
