fix: reqwest can not use SOCKS proxy

[nihao]

#310

• enable feature of reqwest to support socks proxy

[0xMochan]

Hey, thanks for this PR! Is there more details you can describe about your use case with SOCK proxies? I could see this being used for an optional feature or a default feature based on the use case!

[nihao]

Inside our datacenter, the servers cannot access the internet directly. Instead, we provide a SOCKS proxy by default because it offers better speed and stability.

Maybe you can set it as an optional feature, but it will require a convenient configuration method

I think the most ideal way to do this would be to add it as a feature since otherwise, it'll be a breaking change and it would be ideal to keep core dependencies low.

hi @0xMochan , when will you merge this contribute to the project

[joshua-mo-143]

Hi, Mochan's currently OOO at the moment.

If you can set up the socks feature as a separate feature for rig-core rather than including it in the library by default, I'd be happy to merge it. In the interest of ensuring the core library is as lean as possible, it'd be preferred to enable users to opt into features rather than opting out.
