Logger dispatch for SampleBuf type

[shashikdm]

Unsure whether to implement Logger dispatch for SampleBuf. It will result in SampledSignals dependency.

What about using Requires.jl ?

[shashikdm]

That is a nice idea. It'll be helpful with ImageCore, StatsBase, FileIO as well. @oxinabox What is your opinion?

[oxinabox]

Requires.jl is really nice for this in theory.
However, in practice it is incredibly slow, because of how it forces the world to stop to run the compiler.
Also we don't have a great way to handle versions in it AFAIK,

so I would hold off on doing that til other things are done.
