Fix Compatibility issues (fix Pipeline)

[absternator]

The current version 1.2.3 deployed falls over when running on Python >=v3.12 and The CXX compiler GNU) version >=13. Thus the following fixes have been made to ensure it works across these permutations of dependencies. These are both used by conda-forge in the feedstock and therefore should fix current feedstock pipeline woes.

Python >3.12 issues

• in sce.py line 34, pd.Series.to_csv uses sep='\n' which is no longer valid, and thus is removed as this is already the default for the series
• segmentation fault in pairsnp.hpp when checking PyErr_CheckSignals() inside of openmp loop. To fix, Had to ensure this is only checked from the main thread.

GNU 13 issues

• FORTIFY_SOURCE raising compilation errors inside downloaded boost library in /vendor folder. This is due to new compiler version being more strict with these older files. Thus have reverted PR Vendor boost lib #33, so that cmake finds Boost once again. (Have spoken to Rich who created the PR about this)
• conditional_probabilities func in wtsne.hpp was returning 0s and nans causing failure later in "RuntimeError: Probability vector has negative entries" in line 22 of vector_norm.hpp. The reason was because std::numeric_limits<real_t>::infinity() was used for beta_min and beta_max. This infinity causes issues with different compiler versions and thus have changed to use std::numeric_limits<real_t>::max().

Also small type mismatch int & size_t in kseq.h1 that raised warnings. Thus have typecasted to fix.

Note: ubuntu-22.04 uses GNU 11 and ubuntu-latest uses GNU-13. Thus have added as matrix in pipeline

Thanks for this mammoth effort!! All these changes make sense

Sorry about the openmp pyerrcheck one – I'd found that and fixed it in pp-sketchlib after some pain but had forgotten the same was being done here
