Feature: Add support for multiple regex engines

[MikeLemo1]

Useful for anyone who works across multiple platforms, not an expert in regex for now for suffered from the struggle
here's a list of some of the available engines: https://www.regexmagic.com/flavors.html

The ones I used the most are: Vim, Lua, Python, JS, PHP and maybe in the future Golang regex engine.

Does the plugin already support nvim's lua regex btw?

Hello, I'm sorry for the late response, it fully support LUA and PHP but other engines may work too.

Yeah but escaping chars and wildcard expansion inside sets doesn't work it is different than the regex treatment you have in say regex101.com So it's not exactly the same
