oleid, ftguess: parsing issues with PPTM file

[decalage2]

the sample with hash 061e17f3b2fd4a4dce1bf4f8a31198273f1abc47c32456d06fd5997ea4363578 (available on MalwareBazaar) is not parsed correctly by ftguess and oleid:

oleid prints a warning that some XML could not be parsed:
Actually this is because ppt/presentation.xml is an empty file. So this PPTM file is malformed.

oleid 0.60.1 - http://decalage.info/oletools

Filename: 061e17f3b2fd4a4dce1bf4f8a31198273f1abc47c32456d06fd5997ea4363578.pptm
WARNING    xml-parsing for ppt/presentation.xml failed (no element found: line 1, column 0). Run iter_non_xml to investigate.

ftguess does not identify the file format properly:
This is because the MIME type of the main part (ppt/presentation.xml) is "application/vnd.ms-powerpoint.addin.macroEnabled.main+xml", which is not yet supported by ftguess.
=> need to add PPAM, POTX and POTM.

ftguess 0.60.1 on Python 3.11.6 - http://decalage.info/python/oletools
