0.4.0

Changed

• --avoid-type-null is now deprecated, and acts as an alias for --use-nullable-for-merge-patch. This flag now generates complete OpenAPI 3.0-compatible MergePatch types using a clever hack based on nullable: true and oneOf:. It also now sets the file version number to openapi: 3.0.0 when used, because 3.1 does not support nullable: true. Thank you to @hanakslr!
