Add ASDF format

[icweaver]

Hi all, we're hoping to add support for this format which is being positioned as the successor to FITS files in the field of astronomy.

• Spec: https://www.asdf-format.org
• Examples:
  • James Webb Space Telescope
  • Nancy Grace Roman Space Telescope
• Associated JuliaAstro package: ASDF.jl
• PR using it: Some potential QoL improvements JuliaAstro/ASDF.jl#26

Hi all, just wanted to check back in on if there is anything else needed from our end. Thanks!

Nice! I'm guessing the CI failures aren't your fault?

That is my guess, but could be mistaken. Tests past locally, but look to fail on the same tests in CI as other recent PRs here, like for the OGG detection and MATROSKA detection PosixPath tests. I haven't investigated further yet though
