Evaluate additional optimizations like LTO and PGO #5

Hi!

Regarding LTO the issue is pretty much the same as this one: https://github.com/evgenyigumnov/rustsn/issues/53 - just enable LTO for the Release profile. It will likely improve the project's performance and the binary size: according to my tests, at least the binary size is dropped from 9.2 Mib to 7.4 Mib.

Regarding Profile-Guided Optimization (PGO) and similar techniques like Post-Link Optimization (PLO) (with tools like LLVM BOLT - I highly recommend to take a look on them since according to my tests PGO helps to achieve better performance for proxies in C and Rust. If your aim is to squeeze as much performance as possible - definitely worth testing.

Thanks!

If you are interested in testing PGO for the project, I can kindly suggest renaming the issue title and reopening the issue - then it would be a good sign for the community that you don't reject the PGO idea for cblt.
