Better image quality after rotation

Issue #15 resolved
Marek Mauder repo owner created an issue

Received several "complaints" about images after rotation step to be a bit blurry (compared to doing rotation in ImageMagick etc.).

Current "speed over quality" rotation algorithm used in Deskew must be replaced/supplemented with another one.

    Almost done. You'll be able to select sampling method (bilinear, bicubic, lanczos, ...) for the rotation on command line. The default will be bilinear with almost the same speed as the current shear-based rotation but with considerable sharper results (especially with smaller rotation angles typical for deskew).
