Rotate a first order ambisonic signal (B-format) around the z, x and y axes.
The inbuilt equivalent is Rotate2.
The B-format signal, an array: [w, x, y, z]
Rotation angle around z-axis, in radians.
Rotation angle around x-axis, in radians.
Rotation angle around y-axis, in radians.
Output will be multiplied by this value.
This value will be added to the output.
