Help SWAR optimize URI.encode_www_form/1
I had a lot of back and forth with Codex CLI & GPT 5.6 Sol to use a SWAR optimization for URI.encode_www_form/1.
I now have a version that on my machine has no performance regression and has a 1.1X-7x speedup (depending on the input).
This topic is not really close to me and I don’t want to waste the Elixir maintainers time because I might make some trivial mistakes (like I did recently) so I will not submit it as a Pull Request, instead I think it would be great if a member of the community, who understands it much better than me would take this further. Attribution is not important for me, I just want the code to run faster.
