Sean Whalen 5d816a4e56 Offload mailbox layer to mailsuite>=2.0.0 (#741) 
mailsuite 2.0.0 extracted the IMAP, Microsoft Graph, Gmail, and Maildir
connections out of parsedmarc into mailsuite.mailbox so other projects
can reuse the same provider-agnostic interface. Replace the
parsedmarc/mail submodules with a thin re-export of mailsuite.mailbox
and drop the duplicated implementations.

Per the migration note in seanthegeek/mailsuite#22, pass
token_cache_name="parsedmarc" so existing AuthenticationRecord caches
on disk continue to work without re-prompting users to authenticate.
The existing graph_url config knob is forwarded unchanged.

Drop direct dependencies that are now installed transitively via
mailsuite[gmail,msgraph] (msgraph-core, imapclient, google-*). The
extras are pulled in non-optionally so Gmail and Microsoft Graph
support remain available out of the box.

Drop nine test classes that were exercising mailsuite-side
implementation internals (TestGmailConnection, TestGraphConnection,
TestImapConnection, the _get_creds/_generate_credential half of
TestGmailAuthModes, TestImapFallbacks, TestMSGraphFolderFallback,
TestMaildirConnection, TestMaildirReportsFolder, TestMaildirUidHandling,
TestTokenParentDirCreation); these are mailsuite's tests now. The CLI
integration tests that mock parsedmarc.cli.{IMAP,Gmail,MSGraph}Connection
are kept.
