add String method

[mh-cbon]

it is not automated as i wanted initially, but go stringer is not as useful as i thought, and, i was not feeling to rewrite stringer (yet). anyway, it is done.

Hi @mh-cbon thanks for the PR. Took me a minute to realize what this was doing. That was a lot of work!

Only request I have, I am pretty sure that the file contrib/data.yaml is generated by the contrib tests, and probably should not be committed to the repo and also should probably added to the .gitignore files.

What do you think?

[mh-cbon]

all done, i also updated with upstream. thank you for the feedback and merging.
