Outline release roadmap about mephisto

[JackUrb]

Hi @mjkanji, this is a good question. I had intend to do releases when hit certain feature functionality in our milestone roadmap, but priorities have changed so quickly it's hard to do so.

I was erring on the side of PyPI releases occurring only when we have major bugfixes or stable and tested additions. Neither has occurred in full this year yet, as we've been developing new functionality (like prolific) and haven't gotten to test it out internally enough to call it stable.

Hi @mjkanji this is a great suggestion. Given modest size of our team, it may be hard to conceive release schedule well ahead of time. And sometimes some features get a boost based on synergies with our current work needs. We hope to maintain an "undated" roadmap at some point in the future.
