Issue

If I run aider in an environment with all_proxy being set it gives the error below:

Error loading model metadata models: Error loading model definition from
/opt/homebrew/Cellar/aider/0.72.2/libexec/lib/python3.12/site-packages/aider/resources/model-metadata.json: Using
SOCKS proxy, but the 'socksio' package is not installed. Make sure to install httpx using `pip install
httpx[socks]`.

I guess aider should include socksio and https[socks] package in its distribution.
