F# Advent 2021 Dec 08 - Fast data pipelines with F#6

Thanks to Sergey Tihon for running F# Weekly and F# Advent.

Thanks to manofstick for trying out the code and coming with invaluable feedback. Cistern.ValueLinq is very impressive.

There were many interesting improvements in F#6 but one in particular caught my eye, the attribute InlineIfLambda.

Use Onion architecture
- Dependencies go inwards. That is, the Core domain doesn't know about outside layers
Use pipeline model to implement workflows/use-cases/stories
- Business logic makes decisions
- IO does storage with minimal logic
- Keep Business logic and IO separate
Keep IO at edges
