Change get_mue signature to accept numpy arrays #2
Description
The signature of bletl.splines.get_mue currently takes FilterTimeSeries only.
@niklastenhaef can you maybe refactor it so we can pass t, bs just like for the other functions?
That would make it considerably easier to apply it to data of different origins.
The bletl 1.0.0 release is not yet rolled out, so we could make a breaking change if we need to.
