to compress the entire IMAP connection. tested with thunderbird, meli, k9, ios mail. the initial implementation had interoperability issues with some of these clients: if they write the deflate stream and flush in "partial mode", the go stdlib flate reader does not return any data (until there is an explicit zero-length "sync flush" block, or until the history/sliding window is full), blocking progress, resulting in clients closing the seemingly stuck connection after considering the connection timed out. this includes a coy of the flate package with a new reader that returns partially flushed blocks earlier. this also adds imap trace logging to imapclient.Conn, which was useful for debugging.
