Content-Transfer-Encoding in multipart not respected

[mrtnjcl]

I've tried to parse an email where the Content-Transfer-Encoding was specified in the multipart headers, but it was not respected; the Email struct had both TextBody and HTMLBody as raw, undecoded base64 strings.

Content-Type: multipart/alternative;
	boundary="_000_LO2P123MB191986C7932A77EC22F3974AA4290LO2P123MB1919GBRP_"

--_000_LO2P123MB191986C7932A77EC22F3974AA4290LO2P123MB1919GBRP_
Content-Type: text/plain; charset="utf-8"
Content-Transfer-Encoding: base64
