go 1.16.6 net/http breaks HellPot

[yunginnanet]

go1.16.6 and higher breaks HellPot with its changes to net/http

HellPot takes its buffer and begins writing it straight to the http ResponseWriter, but now that ResponseWriter asserts reading the length of the source before it will write the header to our client.

breaking commit: golang/go@cb4cd9e

I am working on rewriting HellPot to use a custom HTTP server that uses raw net.Conn handling, if anyone has a better solution let me know.

Exploring fasthttp as a solution.

See development branch.

As of this commit; HellPot is now using fasthttp. From my (albeit very crude) benchmarks, it's faster, too.
