use tracing crate

[spl0i7]

This commit introduces the tracing, replacing the existing log crate. This commit addresses this issue raised here last week.

Cool :) Thanks for working on this!

Apart from the open question about tracing_subscriber and having to test this a bit more this looks good to go. Tracing should be compatible with log, given the feature is enabled so I think we can land this in a point release.

Oh and according to CI there are a few log references left in tests. https://github.com/magic-wormhole/magic-wormhole.rs/actions/runs/10439844805/job/28909006119?pr=254#step:11:148
