konsti 004147d441 Add tracing_durations_export feature to puffin-cli (#830) ...

The optional `tracing-durations-export` feature allows creating
parallelism plots from all puffin-cli commands without affecting
production builds.

Usage:

```
virtualenv --clear -p 3.10 .venv310 && TRACING_DURATIONS_FILE=target/traces/jupyter-no-cache.ndjson RUST_LOG=puffin=info VIRTUAL_ENV=.venv310 cargo run --bin puffin --profile profiling --features tracing-durations-export -- pip-install -v --no-cache jupyter
virtualenv --clear -p 3.10 .venv310 && TRACING_DURATIONS_FILE=target/traces/jupyter.ndjson RUST_LOG=puffin=info VIRTUAL_ENV=.venv310 cargo run --bin puffin --profile profiling --features tracing-durations-export -- pip-install -v jupyter
 ```
