SD Card Hex to Standard Text File Conversion script

[retiutut]

Is your feature request related to a problem? Please describe.

Some users would appreciate an SD card Hex to human-readable text file for Cyton created files.

Maybe the files should look like the OpenBCI CSV files exactly, mimicking the header information. Something in the script would also need to determine if a Cyton or Cyton Daisy was used.

Describe the solution you'd like

Do this in Python. Shouldn't be that complicated or difficult to run.

Describe alternatives you've considered

Current GUI reads straight from Hex values. Though, some users would like to maybe have a human-readable CSV file that can be used in the GUI or with another program.

There used to be a conversion script in GUI 4.2.0, maybe we should not point users to this, since the data CSV format changed from GUI v4 to GUI v5

So to summarize the current November 2024 status. User roflecopter has created a Python conversion script, done in January 2024. This creates a BDF (not CSV), but EDFBrowser could be used to convert BDF to CSV. And script could probably be modded to produce CSV directly.

And user @Shyamal-Dharia has a GUI / Processing PR that will add a sd file convert feature to the GUI. Also completed and tested January 2024.

I believe both these conversion features should be made available to Cyton users. What is the next step? @retiutut @philippitts
