No option for setting options

[raspofabs]

In InstallCommandBuilderthere is a with_profile and other settings related fluent methods, but there is no method to set options (which are required for using some packages.)

We've worked around this issue for a while locally with environment variables, but it would save us hacking to add something like with_option to set an option.

The recent changes should make it easier to add generic settings passed with -s, I don't recall how conan options are different from settings (what's the command-line notation for options?) but they could be built in a similar way: https://github.com/Devolutions/conan-rs/blob/master/src/build_info/build_settings.rs#L97

Should be resolved by #17. Think we can close
