Release 0.2.33: supprot an actual disassembly of binaries and libraries

[pacak]

Experimental support for disassembly, cargo-show-asm needs to be compiled with "disasm" feature.

With that you can pass --disasm flag to disassemble binary artifacts (.rlib files or executables) created by cargo.

To work with PGO, BOLT or other optimizations that require non standard build process you can pass path to binary directly with --file.

For cargo-show-asm to detect symbols in your code you need to disable stripping by adding something like this to Cargo.toml

[profile.release]
strip = false

At the moment interleaving rust source (--rust) is not supported
