Add support of custom babel rules #28
Description
Hi, thank you for your package. It's great and helps us a lot to migrate our codebase to modern JS style.
In our code we use custom babel plugins, such as @babel/plugin-proposal-decorators
When I apply your tool to our code base, I receive erros, like
SyntaxError: This experimental syntax requires enabling one of the following parser plugin(s): 'decorators-legacy, decorators' (11:0)
How I can fix them?
Thanks!
