Resolves: #1901
Summary:
We had a homegrown parser that only understood numbers, not strings like
MON or TUES. We replace the homegrown parser with cron-parser.
Details:
This was nearly a straight drop-in.
Impact:
Much less code/maintenance burden :D
What I learned:
Don't trust the README, sometimes you just gotta read the code or import
it and try it out. The `fields` representation of the parsed expression
was missing from their docs. I might open an issue or PR to update them!
