WQXValidationService.Rmd is outdated

Is your feature request related to a problem? Please describe:

See note to expand:

This was a placeholder. TADA now handles this in the nearby sites function, though it does not include an option to look for nearby sites only within the same organization (or across all). That might be a nice option to add as a function input.

There are other parts of this vignette that need updating too. For example, we do have a function in TADA that looks for imprecise lat/long.

Describe the solution you'd like:

Review the vignette and update all sections that are outdated.

I like the idea of adding a param to find nearby sites to search only within the same org. I can see that being very useful in some use cases.
