Fix grepl code to remove annual averages

[jjvenky]

scrape_docprofiles() function is allowing annual averages to sneak through

The scrape_docprofiles() function uses a grepl on line 34 to remove the annual averages like "2019 Average" from the bottom of the imported data. This throws warnings so the grepl could be updated to try "Average" as well and handle "Min" and "Max".
