CalibrationSet equality should be sensitive to ordering.

[MarquessV]

#352 made CalibrationSet equality insensitive to ordering. Per Kalan's follow-up, calibration order should be taken into account, as ordering determines precedence when multiple calibrations match the same instruction. The example:

DEFCAL A(%x, pi):
   ...

DEFCAL A(pi, %x):
   ...

A(pi, pi) # expands into one or the other based on ordering
