Adds seqfu@1.22.3

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

• seqfu

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

    maintainers("georgiastuart")

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 seqfu

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.

@dialvarezs this looks like you!

[dialvarezs]

Great! One minor suggestion: the patch should not be necessary for versions 1.22.0 and above (see details here), so you can limit the application to the v1.20.3 version.

Thanks @dialvarezs ! Adding that now. While I'm at it, do you want me to set you as the maintainer?

[dialvarezs]

No problem @georgiastuart ! Sure, you can put me as the maintainer, thanks!
