alamb's review queue

This is my current PR review list. I am putting it on github because:

1. I like how github renders checklists w/ PR titles so it is easy to track (I currently have a local text file...)
2. I thought others might be interested from seeing what I am doign
3. It makes me feel better that I don't have time to review all the PRs 😭

The way I prioritize PRs is in the following order

1. Bug fixes
2. Documentation / UX / API improvements (things that make DataFusion easier/better to work with)
3. Performance improvements
4. New features with wide appeal
5. New functions

Note new features and functions are deliberately at the bottom
