Replace channels-console with hotpath

[pawurb]

Hi, I've deprecated channels-console, it's now part of hotpath. I'm continously working on improving the lib so any feedback and bug reports will be appreciated!

Great thanks for making this PR, and hotpath itself!

The 2 tests which change behaviour based on hotpath feature being enabled fail, I assume because it needs to take into account hotpath-off.

I'm also curious about hotpath-alloc. Is that worth having within kameo, does it affect the channel monitoring?

[pawurb]

Hi, hotpath-alloc does not affect channel! macro only enables mem profiling for functions if you use hotpath::measure. And yes, for --all-features hotpath-off flag causes all macros to be no-op.

Since we're not using hotpath::measure here, I don't think we need to add the hotpath-alloc feature flag in kameo

I've removed hotpath-alloc and hotpath-off features to keep things simple. If users want to have hotpath-alloc enabled, then they can easily enable it in their own hotpath dependency and use hotpath::measure as needed.
