[instancer] udpdate OS/2 class and post.italicAngle when default moved (L4) 
Previously we were only updating these when pinning wght/wdth/slnt axes.
Now we do whenever any of these axes defaults are changed, whether or not the axes are pinned or kept

add custom repr to AxisTriple so they print nicer in the logging output 2022-10-21 18:38:55 +01:00

[instancer] expand singles/tuples to triples upfront and use triples throughout 
Also renamed AxisTent => AxisTriple because I think "tent" is more appropriate to visualize master supports (i.e. a triangle with a peak in the middle), here it's simply the new desired min, default, max values of an axis, or the axis limits.

The public facing instantiateVariableFont continues to accept a hybrid map of axis tags to single values or 2- (and now also 3-) tuples, these are normalized to an AxisLimits mapping that contains only AxisTriples and passed around to the internal methods.
