dace: Add package and version 0.15.1

[tbennun]

This PR adds the DaCe framework as py-dace. It also updates py-aenum to a newer version that DaCe requires in order to work.

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

• py-dace

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

    maintainers("tbennun")

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 py-dace

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.

Confirmed the affected version sha256 for the two packages and the branch for py-dace.

@adamjstewart I fixed all the dependencies (and added ones that were on setup.py but not on Spack). Wherever there is a difference, I pointed it out with comments. This is ready for re-review on my end.

One question, otherwise LGTM

[tbennun]

@adamjstewart Thank you for the thorough review! I think I addressed all the comments now.

[adamjstewart]

Last comment is optional, let me know if you just want me to merge.

[tbennun]

@adamjstewart fixed, thank you for noticing! I think it’s ready for merging
