chore: use tracing instead of log crate

[joshka]

Fixes: #194

Tracing logs for a sample app that hits these -

vs without tracing:

My only hesitancy is for the long-term maintenance of the tracing crate. I know that there was a period where tracing was effectively unmaintained. Looking at the repo it looks like it's maintained better now, but I'm just worried about needing to rollback to log if trading ever becomes unmaintained again.

Looks good to me otherwise.

Fixed a log::warn that I'd missed. The CI still breaks due to the log downgrade. The MSRV of the current version of log (1.60.0) seems to be lower than calloop's MSRV (1.63.0). Does this mean that this is not necessary any more?

The other thing I noted (in #194 in case you missed it) is that this brings back in the proc-macro2 and syn crates to the dependency list (which I saw you were trying to remove by avoiding thiserror).

Yes, it's probably not necessary.

If you import tracing without default features it doesn't have these dependencies though, right?

Actually yep, you're right - I must have checked before I added that

Please rebase on master to fix the CI issues. Then we should be good to go.
