feat: use cross beam channels avoid lock and arc

[Nelsi11120]

Use of crossbeam channels to remove unnecessary lock. And removed Arc not needed too.

Run benchmarks on my side but did not took the time to carefully compare.

Could you please tell me if you get performance improvements @jimzer ?

Thank you!
I run the benchmark and there is performance improvement!

bytes_channel_100 (most impactful):

Time reduced: 101.89ms → 63.78ms (~37% faster)
Throughput increased: 2.40 GiB/s → 3.83 GiB/s (~60% improvement)

characters_channel_100:

Time reduced: 130.04ms → 111.66ms (~14% faster)
Throughput increased: 1.88 GiB/s → 2.19 GiB/s (~16% improvement)

characters_channel_1000:

Improvement: ~8% better throughput (2.42 GiB/s → 2.24 GiB/s in main, staying at 2.24 GiB/s in your branch).

I bumped the version and will merge now!
