If the QRESYNC (RFC 7162) extension is being used, a FETCH response to a
STORE or UID STORE command with the UNCHANGEDSINCE query attribute will
return the mod sequence ID of the performed operation. This information
is crucial for building efficient caching clients.
Use a helper function in `parse_many_into` to support parsing into
any container that implements Extend. Refactor Capabilities to use it.
Delete ZeroCopy and associated bits.
Move Flag into it's own module in types.
* 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
