Improve helper text displayed to user

Call: county_df=getAdmn2ByCountry()

• The counter says things like 144 records retrieved; do you actually mean 14,400 records? Would suggest changing language to either something like "query" or multiplying by 1000.
• It'd be helpful to grab the number of results so you have an idea of how far you are into the function call (e.g. 14,400 out of 68,000)
• Would be nice to add a newline after "X records are retrieved". When there's an error, they get pasted together.
• Might also be useful to display the estimated time remaining in the function. see progress package: https://dplyr.tidyverse.org/reference/progress_estimated.html

To create the progress bar, we need the total number of results which can be obtained from the total field in the object returned by the query,
