[ENH]: Add heudiconv source scripts here

[marcobarilari]

Is there an existing issue for this?

• I have searched the existing issues

New feature

I don't know if there is already a plan to handle heudiconv some how within our environments, if not this repo could be a good target since it is the place where we will have a defacing stap etc to prepare the raw folder

Unclear documentation

No response
