Improve use of max_iter_harmony + max_iter_kmeans

[pinin4fjords]

Hi @slowkow - not a Python pro, but I believe there are issues with how the max_iter parameters are being used in harmonypy. Proposing the following fixes with reference to RunHarmony.Rd:

• Expose max_iter_harmony as top-level argument
• Set max_iter_kmeans default to that of original harmony
• Pass max_iter_harmony to harmonize() to dictate number of harmony runs, rather than max_iter_kmeans (which dictates the number of clusterings within each harmony run).

Obviously apologies if I've misunderstood somewhere.

Thanks for catching this! I will take a closer look soon, but it looks like your changes are correct.

Thanks for the pull request! I fixed a small bug in your code, but that was my fault for the lack of automated testing.

When time allows... I would love to set up automated tests for every commit and pull request.

Ahh, apologies for missing that, thanks @slowkow .

Will you release soon? We're Conda-centric and that will tricker the automatic Bioconda process to produce a new version.

Released! https://github.com/slowkow/harmonypy/releases/tag/v0.0.5
