pypi auto scanner

A github action that periodically fetches the latest pypi packages and scans them using a variety of methods:

• Datadog's guarddog tool (which uses semgrep rules to run static analysis on source code)
• custom yara rules
• running file and detection binary executables
• Sysdig+tcpdump dynamic analysis during install time

Note that the above techniques work well for NPM as well! A NPM equivalent of this repo will be available soon in the future.

Currently stores the JSON report in github action artifacts, *.txt files with a bunch of potentially malicious package names, and raises issues when suspicious packages are found.
