[Feat] - One Degree Rotation

[Canato]

The library today already rotate images using 90, 180, 270 and 360 angles

The goal is to be able to rotate it by 1 degree difference.

For that will be need to auto zoom crop the image:

• Let's say the CropOverlay is the same size as the image.
• When we rotate 5 degrees it will be getting "outside" image area
• So is need to push the CropOverlay inside and create new limits

Add ui rotation selector, like a carrousel from 0-360

Mantis, the iOS library I'm using for cropping has a nice rotation dial (bottom section):
