Release v1.3.0

This release adds a faster and more accurate method to calculate the compound-Poisson thresholds used for ToF data, using a pre-computed table of zero-truncated quantiles. This data was calculated using 10e10 values and should be reliable for alpha values down to 1e-7.
Windowed thresholding of compound-Poisson data is now available using this method.
