Fickling has a detection bypass via stdlib network-protocol constructors

Our assessment imtplib, imaplib, ftplib, poplib, telnetlib, and nntplib were added to the list of unsafe imports https://github.com/trailofbits/fickling/commit/6d20564d23acf14b42ec883908aed159be7b9ade. The UnusedVariables heuristic works as expected. Original report Summary Fickling's checksafety...
