Search by metadata using list_payment_methods

[phstc]

Checking the API docs for list_payment_methods, it supports filtering by metadata, which is very handy, for example, for retrieving all payment methods associated to a user (userId set as metadata).

But checking list_payment_methods implementation, it only supports since_token.

Will this Ruby gem be updated to match with the API docs?

What would be the recommended workaround to adapt (add decorators) this gem to filter by metadata?
