Tracing with puffin!

[siedentop]

Amazing framework. Thanks a lot to the the puffin developers. Thanks to @emilk for helping out

How to use it is described in the Readme:

cargo run --example create_test_file
cargo run --features trace -- binocle_test_file

In another terminal run:

cargo install puffin_viewer
puffin_viewer --url 127.0.0.1:8585

The build failure is persistent also on my forked repo: https://github.com/siedentop/binocle/runs/4194742703?check_suite_focus=true

Issue is on "windows-2019 (x86_64-pc-windows-gnu)", and zstd custom build command is failing.

I would like to just disable the tracing feature for this platform then.

Thank you for making me aware of this framework. This sounds really helpful. However, I'd rather not include tracing support by default here in this project - even if it's hidden behind a feature flag. I'd would try to avoid having to maintain this in the future. This PR/branch is still valuable for documentation purposes though!

Remark: if you want to make code like this optional, you can/should also make the necessary dependencies optional: https://doc.rust-lang.org/cargo/reference/features.html#optional-dependencies

Sounds good to me!
