Add structured results for all values using imap-proto (#58)

* First stab at structured types (#28)

Tests currently fail due to djc/imap-proto#2.

LSUB is also broken due to djc/imap-proto#4 (but we don't have tests for
that atm).

* Also parse out RFC822 fetch responses

* Make all the things zero-copy

* Also delegate IntoIterator for ZeroCopy ref

* Fix UNSEEN and LSUB

All tests now pass

* Address @sanmai-NL comments

* Correctly handle incomplete parser responses

* No need for git dep anymore
