Adding support for .set and .mff files

[jesscall]

Brief summary of changes

This PR adds support to the Wizard for handling .set and .mff files.

Workflow for HBCD purposes:

1. A user must select the file format they wish to run through the Wizard.
2. For MFF, the user can upload multiple MFF directories. These should all come from the same task, just different runs.
3. The MFF files are converted into SET by launching a MATLAB executable (./tools/mff_to_set.exe).
4. The generated SET files will be used by the Wizard to begin BIDS-ification.

❗ Caveats + Dependencies: ❗

• The MATLAB executable can only run on a Windows machine.

• The MATLAB executable requires download of a MATLAB Runtime Compiler R2017b (9.3) - Windows Download

• [ ] Have you updated related documentation?

Testing instructions (if applicable)

1. For Windows: Contact @jesscall to get a hold of a testing packet.
2. For other platforms, test functionality of EDF and SET file BIDS-ification without MFF conversion (not supported)

Notes on debugging the build for Windows:

Need to downgrade the following packages to specified versions:

Jinja2==2.11.3
MarkupSafe==2.0.1

I'm having issues with the MFF_to_SET.exe to launch in the Windows build. This is odd because I can get it to work if I end the app's python service and manually restart it.

Seems to be related to pyinstaller & subprocess - I tried some solutions outlined in this post, but it seems to break functionality of the mff conversion on the dev build.

Will continue to debug, but I think I might have to find a different implementation for launching the exe.
