update_blacklist.py has been updated to handle multiple reference domains, reasons filtering and min_censures

You can now specify extra domains to pull into your censures. You can also specify only specific reasons to censure (for example, censure only loli and csam). Finally you can now also specify the min_censures to use to add to your list.

For example you might want to use 10 different instances as your trusted censure reference, but only block instances censured by at least 5 of them
