LDES1.0 conformance

[pietercolpaert]

The recently published LDES1.0 specification went into a stable version. I’m working on a compliance test suite now that proves spec compliance of independent implementations. This is a PR that tests this spec compliance using a github workflow, and that fixes failing tests we found.

The tests are added here as a GH action. You can find it here as well: https://github.com/pietercolpaert/ldes-client-conformance-test-suite

This PR has a performance regression. Before merging, let’s analyze where things should be implemented more efficiently

[pietercolpaert]

This PR is now 5.43% faster than its base revision by median throughput. Throughput: 1,292.99 members/s vs 1,226.39 members/s in the base.

I found out that, in order to be spec compliant, that it partly re-implemented extract-cbd-shape, but then also used extract-cbd-shape again, which amounted to a lot of extra work per member. Therefore I added a feature in extract-cbd-shape which made sure it can be used in an LDES compliant way and reused that. The profiler also found further performance gains, which makes this version a bit faster than the main branch.

And now, after some more performance fixes in extract-cbd-shape, we get to these results:

This PR is 11.96% faster than its base revision by median throughput. Throughput: 1,495.44 members/s vs 1,335.65 members/s (base)
