find replacement for buf_redux library

[marcmo]

library is not supported anymore

[AmmarAbouZor]

I think one of the best candidates is the crate bytes
I'll make some research about it and try to replace it while exploring the source code

[AmmarAbouZor]

I don't think we can use the crate bytes to replace buf_redux because it doesn't support handling reading from a file directly but rather it works with in-memory bytes only.

I've found the maintained fork buffer_redux, which still hasn't commited changes on the original code besides updating the dependencies, adding CI Pipelines and applying cargo clippy fixes.

I would suggest trying this crate in a draft PR where we can test it and then we can merge if everything is still working fine. We will need to to merge buffer_redux change in Dmitry's fork as well.

@AmmarAbouZor last time we discussed with @marcmo the possibility to maintain buf_redux crate as well. It isn't a huge lib and already includes some of our changes.
@marcmo it looks like it make sense to make a fork of buf_redux in esrlabs and re-register it also on crates.io. What do you think?

[AmmarAbouZor]

It would be very interesting to maintain the crate, since it's really low level and has its share of low level implementation across different operating systems and unsafe code.
