Implement proxy requests

[teemall]

Having the ability to proxy requests, especially through a dump, could be incredibly handy with a project like this. It doesn't look like proxying requests is on your guys road map, but I would be happy look into implementing this so long as it aligns with the vision of this project.

Hello @teemall,

Implementing proxy support is something we want to integrate in the project.

Any help would be appreciated.

I can see different tasks to do:

• ensure proxies are working in the sync http client (a copy of zig's std client modified to use zig.tls)
• handle proxies in the async http client (the hardest part I guess)
• change browser.zig to inject proxy configuration in http clients
• add a way to configure proxies in main.zig. Is guess using something similar to chrome --proxy option would be good enough
