setting PUBLIC_SUFFIX_LIST_URLS with environment variable

[x0day]

PUBLIC_SUFFIX_LIST_URLS now can only define with the function arguments, can this define by environment?

This would be extremely helpful for managed environments where https connections to the outside may not be possible. A container could be built with a current copy, and being able to provide this at the command line would be extremely helpful.

#197 may be helpful in the meantime. Although it's CLI args, not an environment variable.
