Summarypartition_msg() previously used the msg_parser library for parsing Outlook MSG email files (.msg files). The msg_parser library is unmaintained and has several major shortcomings such as not being able to parse MSG files with 8-bit encoded strings and not reliably extracting attachments.
Use the new and permissively licenced python-oxmsg library instead.
Additional Context
For reviewability purposes, this PR temporarily places the new partition_msg() implementation in new_msg.py and references that implementation from msg.py. new_msg.py will be renamed to msg.py in a closely following PR. This avoids a very messy interleaving of hunks in a diff between the old and re-written partition_msg() implementation.
