Next pycytominer release

[gwaybio]

In #160, several of us discussed a potential release strategy. I'll break out this discussion in a new issue, where we can continue a discussion

Previous discussion

Another important note is that we may want to release a pycytominer version 0.1.5 prior to merging this contribution (this contribution can be pycytominer version 0.2), just to make sure pycytominer is completely up-to-date functionally, in an intermediate, but stable version.

I'll also loop in @d33bs about this decision point. Dave, does this release schedule sound like a reasonable strategy? (Beth, note that @d33bs's #203 PR is to a develop branch, but his #197 is to master.)

If the release strategy looks kosher, then we'll likely want to:

1. ✅ merge Improve Memory Performance Within merge_single_cells #197
2. ✅ Release v0.1.5
3. ✅ merge Add collate.py #160
4. ✅ Release v0.2.0
5. ✅ Update conda package
   a. And resolve Conda recipe to support optional install of cytominer-database conda-forge/pycytominer-feedstock#1
6. Work on develop for future releases

Thank you @gwaybio - sounds good to me! Small suggestion: If using 3 number versioning (v.0.1.5) it may be beneficial to stick with that convention throughout for clarity (v0.2.0 instead of v0.2).
