Meet the GitHub community guidelines

[rob-luke]

As this is a community orientated project I suggest we update the repository to meet the GitHub community guidelines https://docs.github.com/en/communities Most of this work has already been done by @fangq, but I suggest simply organising it as recommended by GitHub. See https://github.com/fNIRS/snirf/community for our scorecard

This will involve:

• [x] Move the contribution guidelines from the README to contributing.md (instructions)
• [x] Add issue and pull request templates (instructions)
• [ ] Add code of conduct (instructions)

I am happy to chip away at this in those times where I am waiting for my code to run 😉
