Fixed Hash-Rate Config

<h1>Description:</h1>
Let the user define a fixed hash calculation rate.<br>
Benchmark the possible hash calculation rate and clamp the user-defined rate between 0 and the possible rate so that the gpu can be usable for other programs simultaneously as well.

<h1>Comment:</h1>

Ideally one should run it 24/7 with max gpu usage for the best results.
Of course I will try to run it as often as possible, however - during the day I am busy with work and such and every now and then I play some games.<br>
Me doing some rather light to mid-heavy work should not stop me from calculating like some 5 - 10 Mh/s (Usual rate: 40 - 50 Mh/s) in the background.
I am here to propose the idea for the home- / gaming-pc users for nanominer.<br>

Let me know how far this would be possible to implement because of course I myself am not a crypto mining engineer - I have no clue about details or implementations 😄<br>
