'''to speed up the program you can include a few things: 1) only parse the total results and sift for the NWT listings to create a separate NWT list 2) Implement processpoolexecutor to use more than one worker to parse the pages 3) find a better way to find the last page so you don't have to make more requests than necessary. This could be either taking the "smallest" "no listings found" page of the pages while excluding the others after the smallest one is found. Or, determining from the request headers whether a page is worth downloading or not 4) using a while loop in chunks of 2-4 pages to find the last page in conjunction with number 3'''
