Support expressions as arguments in invocations

Some Arduino examples for the NeoPixel use this line of code as part of the constructor

Adafruit_NeoPixel strip(numPixels, neoPixelPin, NEO_GRB + NEO_KHZ800);

However, this syntax is not allowed, and is denoted as a syntax error, specifically the sum NEO_GRB + NEO_KHZ800, this syntax is important because this is the common way to set the arguments to the NeoPixel driver constructor

Heres the an example of the constant that is used in the constructor
#define NEO_RBG ((0 << 6) | (0 << 4) | (2 << 2) | (1)) ///< Transmit as R,B,G
