• https://github.com/atenreiro/opensquat/issues/84

This commit also contain performance improvements, by multiprocessing domain squatting check (CPU bound), and multithreading port scans (IO bound), all achieve with Python builtin concurrent.futures library.

As a matter of example, for a domain file containing 40000 entries, and a keyword file of 480 entries:

• before this commit, it took at least 40 minutes for domain squatting check
• now, it only takes 10 min

For the port scan check, it also drastically reduces operation duration.
