How to read "BW Analysis" data (Neurovirtual)?

See original GitHub issue

Describe the new feature or enhancement

When I try to read a file with mne.io.read_raw_brainvision, I get the following error:

ValueError: MNE-Python currently only supports header versions 1.0 and 2.0, got unparsable

Describe your proposed implementation

I need the Brain Vision method to be able to read that version of the header file. If/when you are willing to take a look at this, I can provide the .vhdr file I am using with you. (Right now, I don’t have a file that I can share publicly).

Here is my setup in case it is useful:

Ubuntu 18.04.6 LTS
Python 3.8.12
MNE 0.24.1

Hey @FelipeParreira it would be very helpful if you could:

  1. tell us where/how you got the vhdr/vmrk/eeg files (did you record them yourself? if yes, which equipment did you use, and which recording software - e.g., BrainVision Recorder … which version, etc.?)
  2. share the files (preferably the full set of eeg, vmrk, and vhdr) for investigation

I am somewhat new to MNE and eeg files. This just seemed like the last option I had after reading part of the documentation. If there are other ways to read these files, let me know.
