New feature: Patterns

[VamatoHD]

This is a draft of a new feature that replaces generate_permutations entirely.
It's a small parser I wrote that converts and expands the string based on [<chars>]{<lens>}.

Syntax:

When you want an automatic pattern to be expanded, you use:
[<list of characters>] followed by (optional) {<list of lengths separated by ";">}

For example:

• "john[a-z]" -> "johna", "johnb", "johnc"...
• john_doe[0-9]{0-2} -> "john_doe", "john_doe0", "john_doe1" ... ""john_doe99"

---

TODO:

• Randomizing generation
• Testing
• Improve overall code
• Documentation

@VamatoHD Nice idea, to be honest. The permutation feature was a bit inconsistent, it produced random username and email variations without much control. This approach gives users a lot more control and flexibility.

@VamatoHD I resolved the conflicts in __main__.py. The conflicts occurred because PRs #183 and #184 were opened around the same time, and both modified __main__.py. I’ve fixed and resolved the conflict so take a look and check __main__.py again if it aligns with your pattern implementation.

I've added a function to iterate the usernames/emails randomly.
Sadly, I haven't got much time to improve the code and add documentation.

#184

Hey @VamatoHD, I opened #265 to help with the remaining TODO items:

• Testing: 51 unit tests covering expand_patterns, expand_patterns_random, and a new count_patterns function
• Code quality: 6 fixes (if res: bug, typo, shadowed builtin, etc.)
• Documentation: Docstrings on all public functions
• CLI: Updated the permutation message to show total count (e.g. "Scanning 5 of 111 permutations")

The PR is based on your pattern branch. Let me know if you'd like any changes!
