Initialise an object able to carry out an asinh mapping @param minimum Minimum pixel value (default: 0) @param dataRange Range of values for stretch if Q=0; roughly the linear part (default: 1) @param Q Softening parameter (default: 8) See Lupton et al., PASP 116, 133
Reimplemented in lsst.display.matplotlib.matplotlib.AsinhZScaleNormalize.

Return an asinh mapping's minimum and maximum value, and Q Regrettably this information is not preserved by AsinhMapping so we have to reverse engineer it
