Functions to compute L1 distance #133

Open MBkkt opened 5 months ago

MBkkt commented 5 months ago

Manhattan distance sometimes useful

Already done for bit (hamming)

This might be interesting for i8 inputs and any other low-capacity integral types, and might be related to #100 for sparse distances
