Is there an existing issue for this?

New feature

Since the output is an `.edf` under-license extension and the below snippet of code works only on windows (and we don't like it), it is nice to take advantage of the windows computer in the MRI and convert it right away in ASCII `.asc`. Then open source pipelines can make a `tsv` version of it.

Code is in matlab, it is ugly and needs reformating. See [here](https://drive.google.com/drive/folders/1IZIszvDCPhtOhW65OthoPekXrfRA8zmX?usp=sharing) for an example, it also requires `edf2asc.exe` and `edfapi.dll`
