New feature: ignore same endpoints with different parameters

[caioluders]

Hi !

While doing bug bounty I sometimes don't want to see duplicated endpoints with the only difference being the parameters, so I wrote this option.

I was concerned that creating a new map that stores every URL would be memory intensive, but did some profiling with pprof and it doesn't seem to affect the tool too much.

I think that the description/name of the "--fp" option can be improved, feel free to modify it.

Thanks, great tool (:
