re2c: add versions

Hi @jrood-nrel! I noticed that the following package(s) don't yet have maintainers:

• re2c

Are you interested in adopting any of these package(s)? If so, simply add the following to the package class:

    maintainers("jrood-nrel")

If not, could you contact the developers of this package and see if they are interested? You can quickly see who has worked on a package with spack blame:

$ spack blame re2c

Thank you for your help! Please don't add maintainers without their consent.

You don't have to be a Spack expert or package developer in order to be a "maintainer," it just gives us a list of users willing to review PRs or debug issues relating to this package. A package can have multiple maintainers; just add a list of GitHub handles of anyone who wants to volunteer.

@johnwparent Are you interested in reviewing this PR as someone who made significant changes to the package within the last year?

Yes, thanks, re2c is critical for Windows in order to bootstrap clingo without issue (since we have no cached clingo ATM) so it'll be good to review this, thanks for the ping!

Gitlab failure is legit:

==> Error: ProcessError: Command exited with status 1:

Looks like the new versions require some additional logic re: python.

Once the Gitlab pipeline passes I'll validate Windows by hand.

@jrood-nrel We need further constraints to bootstrap clingo on old python versions. I can look into that next week, if you don't have bandwidth.
