read_citations doesn't allow for only_key_fields to take on a character vector

[TNRiley]

CiteSource::read_citations is supposed to allow users to select only_key_fields as either TRUE, FALSE, OR to add a character vector to identify fields they want to retain.

I don't believe the character vector option works due to the fact that CiteSource::read_citations inherits the parameters of synthesisr::synthesisr_read_refs and this function's argument "select_fields" defaults to NULL (which means it will read in all fields of the RIS)

@LukasWallrich do you read this the same way I do?

Sounds plausible but I'd need to test it. I hope to get to it next week.

@TNRiley the character vector works for me (see below). Did you run into any particular issues?
