The stdlib ReverseProxy from net/http/httputil has 2 issues that this project solves

1. There is single host proxy provided by NewSingleHostReverseProxy, but there is nothing to create a multi-host proxy
2. While it's possible to process a request before sending it to the proxy, the standard proxy doesn't provide a way to process the proxy response before flushing it out to the clients.

moxy aims to solve both of these problems by

1. Providing moxy.NewReverseProxy, that supports load-balancing across multiple hosts
2. Adding suppport for moxy.FilterFunc, a chain of functions that run over the proxy response & optionally make changes to it, before sending it back to the clients.
