Does rust-imap parse things twice?

> It seems like a common pattern in the codebase is to use `run_command_and_read_response`, and then parse its output. However, `read_response` already fully parses the response, its just that the results of the parsing seems to be discarded https://github.com/mattnenterprise/rust-imap/blob/master/src/client.rs#L521.
