Throw error if called from an incompatible version of tidyquery

[ianmcook]

tidyquery imports queryparser and can require a minimum version of queryparser through R's usual method of specifying forward import versions. But this leaves open the possibility that a user might upgrade to a new version of queryparser but still have an older, incompatible version of tidyquery.

When queryparser is called from tidyquery, check its version and throw an error if the version is incompatible.

To avoid needing to add utils to the queryparser dependencies, this exports the version number from tidyquery so we don't need to call utils::packageVersion() in queryparser: ianmcook/tidyquery@cef958e
