v0.17.0

The Go module path moves to github.com/stricttools/howmuchleft, and howmuchleft now builds on strictcli 0.38 and go-toml-edit 0.5 at their stricttools paths.

Breaking

• The Go module path moved to github.com/stricttools/howmuchleft. The repository lives in the stricttools organization, so github.com/smm-h/howmuchleft is no longer this module's path: install with go install github.com/stricttools/howmuchleft@v0, and a program importing its packages changes its imports and require to the new path.
• howmuchleft version is now strictcli's framework command and prints howmuchleft <version> instead of the bare version number, and it no longer runs the settings migrations. Scripts that parse its output must take the second word.
