browser logging env filter - configure log filters by package

[johnny-smitherson]

It's often that we pull some dependency that spams the logs at warning level. In current dioxus logger implementation, customization of tracing env filters only works on the server using RUST_LOG env var. But it's not possible to do this on the browser as the dioxus::logger::init method does not expose env filter customization.

I found that on wasm filters can be passed in with:

...
        let filter : tracing_subscriber::EnvFilter = env_filter.parse().unwrap();
        let reg = Registry::default().with(layer).with(filter);
...

And the logs are filtered according to the rule.

Do you think this init_with_env_filter or something similar would be added to upstream ?
