Support for adding history of commands to header

[eurunuela]

I use AFNI's 3dNotes -h "{command}" {filename} command a lot but it requires the use of subprocess.run() to run it from Python.

I believe nibabel should provide this feature in a Pythonic way, similar to the way other parameters of the header can be edited.

I would need to check if we support writing BRIK/HEAD. My memory is that it's read only, but maybe not.

If this also works in the AFNI extension to NIfTI-1, then we would need to add support for that extension. Is there a spec?

I'm any case, would you be interested in adding this feature?

Thank you Chris.

Please let me know.

I'm not sure I understand what you mean by the AFNI extension to NIfTI-1.

I would be happy to contribute, but I will need help from core devs. This is the first time I fork nibabel and look at the project.

I will try to familiarize with the I/O functions first and will open a PR if (when) I make any progress.

There are header extensions to NIfTI, and AFNI has one that includes the additional metadata from BRIK/HEAD that the AFNI team felt were essential but missing.
