test: mv algorithm tests to subfolder

[tristan-f-r]

The result of

mkdir test/algorithms
git mv test/AllPairs/ test/BowTieBuilder/ test/DOMINO/ test/LocalNeighborhood/ test/MEO test/MinCostFlow/ test/OmicsIntegrator1 test/OmicsIntegrator2 test/PathLinker/ test/ResponseNet/ test/RWR/ test/ST_RWR/ test/algorithms/

with manual changes for file paths.

This is a convenient change for #364, as it helps the Windows CI ignore the unrunnable docker containers (see #23). We may also want to do this for the actual spras source code, but that's more refactor-heavy than this.

How did this help #364? I wasn't clear on why we ignore so many tests on Windows, which we could discuss there instead of here.

We ignore all of the algorithm tests on #364: this PR means we don't need to manually list every single algorithm one-by-one.
