• [x] Each commit and PR title has a valid :memo: <package name>: title first line subject for packages
• [x] Incremented :up: any PKG_VERSION in the Makefile (package does not have one?)
• [x] Tested on: (x86, 64, openwrt-23.05.4, Firefox 124) :white_check_mark:
• [x] Mention: @sbyx, @jow-
• [x] Screenshot or mp4 of changes:
• [x] Depends on: openwrt/packages#24713
• [x] Description: tinyproxy supports several Bind options, that can be used to create a proxy that (1) supports both IPv4 and IPv6 and (2) uses specific addresses (in my case VPN addresses. It is very important to bind to specific addresses to avoid traffic leaks).

The app was converted to JavaScript with https://github.com/openwrt/luci/commit/bbb08197c51daa388633437bf14fc15f91227e34 so once the PR in packages gets accepted you would need to rebase and re-implement it in JavaScript, should be trivial tho.

@Ramon00 maybe you can take finish the PR?

I can make new PR I guess, but the underlaying app did not get updated yet. So we cant merge this right now anyway.
