Release v1.0.0

Release v1.0.0

This package has been stable for several years with no bug reports in that
time. It is also pretty much feature complete. I am therefore updating the
version to 1.0.0.

Because this is a major release, all previously deprecated code has been
removed from the package.

Breaking changes

• Removed the TimeV function. Use Time or QueryWithOptions instead.
