Refactored APIs

• resizedTo(width:height:interpolatedBy:) without CoreGraphics
• rotated(by:), rotated(byDegrees:) and rotated(by:interpolatedBy:), rotated(byDegrees:interpolatedBy:)
• Renamed write(to:formatting:) to write(to:format:) following write(to:options:) of Data
• Renamed ExtrapolationMethod cases
  • .edging to .edge
  • .repeating to .repeat
  • .mirroring to .reflection

---

Note: Some more renaming are still under consideration, e.g. ExtrapolationMethod to PaddingMethod and subscript(_:_:interpolatedBy:extrapolatedBy:) to subscript(_:_:interpolation:padding:).

Some additional convenient APIs

• rotated(by: angle, ...)
• subscript(xRange, yRange, extrapolatedBy: extrapolationMethod)
• write(to:...)
• data(using:)
• AnyImage<Pixel>

`ImageProtocol` makes `ImageSlice` more powerful

Now ImageSlice has a lot of APIs which Image has had: interpolation, extrapolation, convolution, operators and so on.
