check-Asimov-NIBs

Pre-requisites:

• python 3.8.5
• pip install requests
• create 2 subfolders: NIBs & NIBZIPs
• download site_index.txt from here

Limitations:

• zipped .nibs are skipped (but copied to NIBZIPs)
• there are a few false-positive matches for .nibs (eg. MoonPatrol.nib.asm, threshold.nib.readme), which are harmless
