Use []uint32 instead of imap.SeqSet
A sequence-set is an IMAP-specific implementation detail. Throughout the UI, aerc simply operates using lists of opaque identifiers. In order to loosen the coupling between the UI and IMAP in particular, replace most usages of imap.SeqSet with []uint32, leaving the translation to a SeqSet to the IMAP backend as needed.
