Add code to support %DOMAIN% tag replacer

[nrathaus]

Description

What will it do?

If this PR will fix an issue, please address it:
#1313

if it finds a %DOMAIN% tag inside the dictionary, it will replace it with the hostname field of the URL - if multiple URLs are provided it will replace it multiple times

Hi! Glad to meet you @nrathaus ! How you doing?

I like it but I wonder, for example if type www.example.com:

• Shouldn't try example.com?
• Or just example?

For example, given the case "%DOMAIN%.zip":

• www.example.com.zip
• example.com.zip
• example.zip

@maurosoria I added the iterator so that it will go through the components of the domain

Let me know if this is what you were expecting

Hi again!

I see you got me but there are 3 issues with your commit:

• What happens when a line has both %EXT% or %DOMAIN% in the same line (or any other future tag)? I see in this commit you only allow one tag per line
• domain can be parsed before entering the loop in line 125 (also you can use tldrextract or a regexp to parse the domain)
• Same behaviour should be applied at line 196

Thanks for your quick response. If you feel I am too demanding please tell me. I Like your patch (I also like other ones like %YEAR%!!!)!

I did a one tag replacer because EXT had a similar design, to support multiple tags - we would need to rewrite the whole function used - I am ok with doing that

Regarding tldrextract, I didn't want to introduce another library - we don't actually need this in my opinion, just dot breaking is sufficient for this dirsearch improvement

I added additional code, didn't get a chance to test it yet - will try to do it later
