"chunked" results. This removes the need (usually) to search and then
manually open a cheatsheet.
- Deprecates the `Match` struct
- Applies syntax highlighting to search results output in a manner
consistent with the 'View' output
- Refactors search to move colorization functionality outside of its
concern
- Re-implemented the project in Golang, and deprecated Python entirely
- Implemented several new, long-requested features
- Refactored cheatsheets into a separate repository
