Allow `IOptions<SassCompilerOptions>`

[gumbarros]

I'm getting sass executable not found on IIS. (Runtime Sass compilation)

Solved with deploying the executable and this:

using AspNetCore.SassCompiler;

[assembly:SassCompiler("Sass\\dart.exe","Sass\\Sass.snapshot")]

Please allow an IOptions<SassCompiler>with the path, this feels so hacky
