Hyp3lib

Fixed
* Support Python 3.13 by replacing the `cgi` module with the `email.message` module as described in [PEP 594](https://peps.python.org/pep-0594/#cgi). Fixes <https://github.com/ASFHyP3/hyp3-lib/issues/300>.

Fixed
* Pin Python version to `<3.13` because the standard library [`cgi` module](https://docs.python.org/3.12/library/cgi.html) has been removed in Python 3.13. See <https://github.com/ASFHyP3/hyp3-lib/issues/300>.

Removed
* Support for Python 3.8 and 3.9 has been dropped, 3.10 is now the minimum version.
* The `six` package has been dropped as a dependency as it's no longer used since we don't support Python 2 anymore.

Changed
* `hyp3lib` now uses a `src` layout per this [recommendation](https://packaging.python.org/en/latest/discussions/src-layout-vs-flat-layout/).
* `hyp3lib` now only uses `pyproject.toml` for package creation now that `setuptools` recommends [not using setup.py](https://setuptools.pypa.io/en/latest/userguide/quickstart.html#setuppy-discouraged).
* Updated GitHub Actions to current HyP3 standards.
* Updated formatting using Ruff to pass flake8 check.

Removed
* Support for Python 3.7 and 3.8 has been dropped in line with NumPy and the larger scientific python ecosystem, as described in [NEP-0029](https://numpy.org/neps/nep-0029-deprecation_policy.html) and [SEPC-0000](https://scientific-python.org/specs/spec-0000/)
* All hyp3lib functionality not currently being used by one of these GitHub orgs: ASFHyP3, asfadmin, ASFOpenSARLab, access-cloud-based-insar, dbekaert, ASFBinderRecipes, or insarlab. For a full list of the deleted files, see [here](https://github.com/ASFHyP3/hyp3-lib/pull/286).
* Removed now unused dependencies from `pyproject.toml` and `environment.yml`.

Fixed
* Install `build` dependency to fix `distribute` action.

Fixed
* `distribute` action to use updated version similar to `hyp3-sdk`
