Function to categorize flows
To assist with plotting functionality and using hyswap for mapping flow conditions, we should add a utility function to categorize flows based on a particular scheme. Possible schemes are in #21 (closed) but could also include other schemes.
Will need to decide if hyswap should have schemes built-in as options, or is just a user input.
Three components would make up a scheme:
- Ranges of streamflow percentiles that form categories
- Labels for categories
- Color palette
