Error loading Source 2 SFM session DMX file with datamodel.py
Hi, I'm encountering an issue when trying to load an SFM session with datamodel.py originating from the Dota 2 SFM.

Repro steps:
1. Install Dota 2 Workshop Tools
2. Open Dota 2 SFM
3. Create new session and add any random model as an animation set
4. Save session
5. In Python:
import datamodel as dm dm_object = dm.load('path/to/session.dmx')

Result:
Traceback (most recent call last): File "<stdin>", line 1, in <module> File "datamodel.py", line 1073, in load read_element(elem) File "datamodel.py", line 1039, in read_element attr_type = _get_dmx_id_type(encoding,encoding_ver,attr_type_id) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "datamodel.py", line 453, in _get_dmx_id_type return eval("_" + attr_list_v3[id-32].__name__.capitalize() + "Array") ~~~~~~~~~~~~^^^^^^^ IndexError: list index out of range

The file header is <!-- dmx encoding binary 9 format sfm_session 22 --> but I suspect that this is to do with this branch of source 2 using a different binary encoding than previously supported by datamodel.py. Converting the file to keyvalues2 format using dmxconvert allows me to load it without issue, but I'd like to be able to read the binary files directly if possible.

This doesn't affect model import/export so I won't create a new release of the tools.

Please upload a DMX file which demonstrates this problem.
