Support for different features sets at build/install time

[bra-fsn]

Doing a cargo install takes ages for example on x86 based arm64 GHA builders due to the huge number of dependencies.
It would be great if binserve could be installed/built with only the required features and their dependencies. For example for plain static file serving, requiring the very heavy (to compile) minify_html_onepass, lightningcss etc crates are unnecessary.
The best of course would be to have different features to be enabled/disabled, but for me, a stripped down minimal version for doing static file serving would be enough. :)
May I ask for this to be considered?

Thanks!
