CloudFlare bypass

[bmirnoff]

I think we need to add Cloudflare bypass https://github.com/MHProDev/MHDDoS/blob/2cd27e8b645d0dbf05048fa0e295844dc65a0671/start.py#L738
Also it might be configurable

yeah, I've been looking into it. it would require either adding python or javascript interpreter to be able to properly run checks, I have some ideas but need some more time to reflect on them. I've been looking at https://pkg.go.dev/github.com/robertkrimen/otto as it's written purely in go and we don't need performance from the javascript module and pure go is easier to maintain (I've seen 4 other js engines for go, all of them had more performance but were just providing bindings for C/C++ code and 3 of them are currently archived)

@arriven Sound good, otto for me also looks like a promising solution. I also can investigate this direction and share ideas here

@bmirnoff what would probably be most important (especially in terms of using otto) and what I didn't have a chance to check yet is whether the anti-bot check requires an event loop or if it is just a simple evaluation and the timeout can somehow be parsed from the page/code
