JWE3 - Manis Format

[calpotter]

Describe the bug
This GUI error happens when opening .manis files in the Manis Editor programme. When loading the individual files within the Manis file it gives an error and states this.

ERROR | GUI update failed, see log!
Traceback (most recent call last):
  File "E:\Downloads\Tools\cobra-tools-master\cobra-tools-master\manis_tool_gui.py", line 282, in update_gui_table
    dtype_array = getattr(m.keys, f"{dtype}_names")
                          ^^^^^^
AttributeError: 'ManiInfo' object has no attribute 'keys'

To Reproduce
Steps to reproduce the behaviour:

1. Open the manis_tool_gui.py and set the game to Jurassic World Evolution 3
2. Click on ''File' and open the .manis exported previously with the OLV tool
3. An error will pop up in the GUI stating "GUI update failed, see log"@
4. Go to the command window that was opened when you opened the tool. See error there.

Expected behavior
I expected for the file to open within the GUI and I would be able to decompress the manis so I could use it in Blender.
