Compute fuzzy breaks
For a continuous scale, fuzzybreaks "preserve" the range of
the scale. The fuzzing is close to numerical roundoff and

Parameters
----------
scale : scale
Scale
breaks : array_like
Sequence of break points. If provided and the scale is not
discrete, they are returned.
boundary : float
First break. If `None` a suitable on is computed using
the range of the scale and the binwidth.
binwidth : float
Separation between the breaks
bins : int
Number of bins
right : bool
If `True` the right edges of the bins are part of the
bin. If `False` then the left edges of the bins are part
of the bin.
