there should be an error for one changepoint with one data point

[tdhock]

hi @diego-urgell in your edge case test file I see

ans <- BinSeg::BinSegModel(100, "BS", "mean_norm", 1)

There is one data point (100) with nCpts=1 (fourth argument), so there should be an error. It is not possible to compute any changepoints if there is only one data point.

Right, it makes sense since it is not possible to "partition" the dataset if there is only one data point. Thanks!
