feat: protect users against ReDoS

[NanderTGA]

ReDoS vulnerabilities are a serious problem and people using regex prefixes could fall victim to this.
I want to protect people against this by checking for ReDoS vulnerabilities in the background using recheck.

It does add an extra dependency though.
Do or don't?

yes, but if you can, do something so we can disable it in the Client, like new Client("testbot", [ "e" ], { recheck: false })

Yeah, I was planning to do that.
