…lly check the max length dynamically zero pad ceil(log10(maxlen)) zero padding would do but maybe we should store a new "maxlength" key

Beginning of the implementation of the DTW and FastDTW algorithms now that #247 allows time-based manipulation, the pr is mostly for discussion about interface until something functional is built (branch
data-seriesmerged in from lewardo/flucoma-core@7d15aaf)Interface is still up for discussion, since it is merely a complicated but funkier version of a distance between two tensors (take that pythagoras). Algorithms such as
KMeanswould benefit very much from this algorithm, henceDTWandFastDTWbeing functors is an interesting paradigm to explore, so that there is not as much refactoring for distance-using objects.As a proof of concept it will be the distance algorithm used in the
kNearestinterface indataSeries(as provided bydataSetwith squared euclidian distance)
