4-colors Benchy (AMS test)

4-colors Benchy to test AMS capabilities. Default profile comes with disabled prime tower and is rotated to layer's alignment for fast printing and minimal waste. Based on original Benchy by Daniel Norée (danielnoree.com, 2015), multi-color version inspired by h2c-17-color-benchy. I rotated the original Benchy and divided it into subparts for a nice 4-color AMS print with minimal number of color changes.
