Bump isal from 1.7.2 to 1.8.0

[dependabot]

Bumps isal from 1.7.2 to 1.8.0.

Release notes

Sourced from isal's releases.

version 1.8.0

• Python 3.14 is supported.
• Python 3.8 and 3.9 are no longer supported.
• Fix an issue where flushing using igzip_threaded caused a gzip end of stream and started a new gzip stream. In essence creating a concatenated gzip stream. Now it is in concordance with how single threaded gzip streams are flushed using Z_SYNC_FLUSH.
• Change build backend to setuptools-scm which is more commonly used and supported.
• Include test packages in the source distribution, so source distribution installations can be verified.
• Fix an issue where some tests failed because they ignored PYTHONPATH.
• Enable support for free-threading and build free-threaded wheels for CPython 3.14. Thanks to @​lysnikolaou and @​ngoldbaum.
