feat(types): move Emigrate types to separate package and improve types (#41)

* feat(types): move Emigrate types to separate package

Also refactor the types to use discriminating unions for easier error handling and such.
Errors passed to storage plugins should now be serialized and storage plugins are expected to return already serialized errors on failed history entries.

* fix(mysql): handle the new type changes

* fix(storage-fs): handle the new type changes

* feat(cli): better error handling and types

Adapt to the new types from the @emigrate/types package, like discriminating union types and serializing and deserializing errors

+# @emigrate/types
+
+## 0.7.0
+
+### Minor Changes
+
+- bad4e25: Pass the Emigrate CLI's version number to reporters
+
+## 0.6.0
+
+### Minor Changes
+
+- a79f8e8: When serializing errors take all "own properties" into account to be able to serialize errors thrown by the `mysql2` package for instance without losing any information
+
+### Patch Changes
+
+- a79f8e8: Serialization of errors now happens inside storage plugins because it makes more sense and the types are easier to work with this way
+
+## 0.5.0
+
+### Minor Changes
+
+- 703e6f0: Add "end" method to storage plugins so they can cleanup resources when a command is finished
+- c1d5597: Add serializeError utility function for serializing Error instances
+
+## 0.4.1
+
+### Patch Changes
+
+- 20ed2e8: Try importing plugins (and reporters) using prefixes before importing without, this is to avoid issue with accidentaly importing other non-emigrate related packages. E.g. setting the reporter to "pino" would import the "pino" package without this fix and will import "@emigrate/reporter-pino" with this fix.
+- d916043: Fix a regression issue where plugins wasn't correctly loaded if specified as strings
+
+## 0.4.0
+
+### Minor Changes
+
+- 5e8572b: Pass the current command to the reporter
+- 8e87ade: Move storages and reporters out from the plugin option into their own separate options (i.e. "--reporter" and "--storage" respectively). This makes it easier to change the interfaces of storages and reporters, and it's also more similar to other tools.
+- 672fae1: Include "@emigrate/" in the plugin prefix list, i.e. when searching for the plugin "blaha" it will look for the packages "blaha", "@emigrate/blaha", "@emigrate/plugin-blaha" and "emigrate-plugin-blaha" and use the first of them that exists
+- d8a6a24: Implement the "remove" command for removing migration entries from the history
+
+### Patch Changes
+
+- 60ae3b8: Fix loading of lazy loaded plugins with default exports
+- acb0b4f: Keep upper cased letters in migration file names by default
+
+## 0.3.0
+
+### Minor Changes
+
+- 8f35812: Add support for "reporter" plugins and implement a simple default reporter
+
+## 0.2.0
+
+### Minor Changes
+
+- 23a323c: Add the convenience functions `getOrLoadPlugin` and `getOrLoadPlugins`
+- 62bd5a4: Add more properties to the MigrationMetadata type to ease writing "loader" plugins
+- 81fde2e: Prepare for supporting "loader" plugins. A loader plugin is used to transform a migration file of a given type (file extension) to a function that will execute the actual migration.
+- 9f5abf7: Simplify plugin interfaces by getting rid of the "type" string, in preparation for having packages that contains multiple different plugins
+
+### Patch Changes
+
+- 1799b6e: Add missing types and utility methods related to the new "loader" plugins
+- 3e0ff07: Specify files to include in published NPM package
+
+## 0.1.1
+
+### Patch Changes
+
+- 50fce0a: Add some simple README's for each package and add homepage, repository and bugs URLs to each package.json file
+
+## 0.1.0
+
+### Minor Changes
+
+- cdafd05: First version of the @emigrate/plugin-tools package which contains some nice to have utilities when building and using Emigrate plugins
+- 9c239e0: Use import-from-esm to resolve plugins relative to the current working directory and add a convenient plugin loader helper (loadPlugin)
+
+### Patch Changes
+
+- 1634094: Remove double and trailing underscores in sanitized filenames and lower case the result for consistent filenames
