Hello, is there any issue in merging this? Please let me know

I'm a user of this python client, and I couldn't see any good documentation around what should the bank_name be really, but it looks like it's intended to be a free substring to search for.

Replacing in by == would make the search much tighter potentially breaking users who are using it as a substring search. Because we can't know what the bank_name should be exactly, I am against merging this PR.

If it is indeed intended to be a search, however, this code should return multiple institutions, all matches against the institution: str parameter.
