This migration library was in dire need of an update, to make it easier to maintain and use.

Changelog

Functionality has been encapsulated, so that migrations can be managed for multiple databases without trampling each other's configuration.
Migrations now need to be registered in a Registry object.
- This does mean that the pattern of globally registering migrations in init() methods no longer work. The workaround is to define a Registry (by value, not pointer) in the package where migrations are generated. The zero-value of the registry is ready for use, so it doesn't need special initialisation.
- The Registry should be thread-safe.
Functionality is now accessed by running methods on a Migrator. This should be easier to use than emulating command-line arguments without proper type-checking.
Case conversion now allocates fewer strings.
Configuration is achieved by the options pattern. Any of the With*() functions can be called and passed to the Migrator's constructor as additional arguments.
The package now defines a number of errors, which can be easily checked with errors.Is() from github.com/pkg/errors.
