[RFC] Writing a new, even more minimal implementation vs optimizing picoweb (with not backward compatible changes)

[pfalcon]

There's growing need to make a choice for subj.

My idea: Writing another one only fragments the space. While a complete reimplementation may be needed eventually, doing incremental changes is almost always a better approach.

So, going to introduce a "breaking change" label to kinda pre-announce upcoming refactors: https://github.com/pfalcon/picoweb/labels/breaking%20change
