Invert color of Apriltag

[HappySamuel]

Hi

Does the current apriltag_ros support inversion color of apriltag? Black and white inverted with each other.
If it doesn't support, and i would like to invert the color of apriltag, which area of code shall i amend to make it work? All the tag ID are still same as before, just color inversion.

Best,
Samuel
