feature/option-value-formatting

roanutil · roanutil · commit 75dfc22f660a · 2024-02-15T08:43:01.000-06:00
- Change SeparatorFormatter to take the key and value as arguments and return an array of strings. This is what I think most would expect and works better with `Process` which seems to be picky about an option's key and value being separate elements in the array.
- Rename BodyFormatter to KeyFormatter which is a more clear name
- Rename SeparatorFormatter.space to separate which is a more clear name
