* Add flag to display the version for each binary. It is based on `git describe` but adds a number to the PATCH level if we are between annotated tags, so makes it semver.org compatible. Use the "-ldflags" method that also works with go 1.17. * Use Makefile bash and sed magic to do PATCH level increase if needed. Co-authored-by: Bernhard Reiter <bernhard@intevation.de>
