Update sigmf schema to v1.2.5

[777arc]

haven't tested anything on the python side yet. @daniestevez this is for you =)

Thanks for addressing this so quickly! I've just tested our internal application with sigmf-python from this PR branch and it works correctly.

You guys were so fast you forgot to update __specification__ in __init__.py.

[777arc]

Ah my bad, is there a way we can have that read from the schema file somehow?

Or at a minimum we could have a little github action that makes sure they always match 😄

If we do this we will also need to do that in docs/source/conf.py because it also reads the specification dynamically.

If the Sphinx docs are built with sigmf-python installed, then we can pull this information directly from the Python package. Example: https://github.com/maia-sdr/pm-remez/blob/main/sphinx/source/conf.py#L16 (this is a Python package implemented in Rust, but for it doesn't make any difference for this). Probably the sigmf-python is already available when Read The Docs builds the docs. I've checked this pm-remez package to see if I configured anything in .readthedocs.yaml to make this happen, but I don't see anything special.

I've given this a shot in #110, but someone with read the docs admin access should check that the docs from that PR branch can be built successfully.
