le16enc is documented to work any alignment... from byteorder(9):
The be16enc(), be16dec(), be32enc(), be32dec(), be64enc(), be64dec(),
le16enc(), le16dec(), le32enc(), le32dec(), le64enc(), and le64dec()
functions encode and decode integers to/from byte strings on any
^^^
alignment in big/little endian format.
