aioimaplib stores RFC822 literal data as bytearray in response.lines,
not bytes. The extraction loop checked isinstance(line, bytes) which
returns False for bytearray, silently dropping every email body and
causing all IMAP emails (T-Online, GMX, etc.) to appear empty.
Fix: accept (bytes, bytearray) and convert to bytes() immediately so
the rest of the pipeline is unaffected. Two new regression tests mirror
the real aioimaplib behaviour by passing bytearray as the literal.
