[RFC]: Canberra distance between two strided arrays

[Planeshifter]

Description

This RFC proposes adding a function to calculate the Canberra distance between two strided arrays.

Package: @stdlib/math/strided/distances/canberra

The function should have the following signature canberra( N, x, strideX, y, strideY ).

The Canberra distance is a measure of dissimilarity between two samples in a data set.

The Canberra distance between two elements is as follows:

(abs(x[i] - y[i]) / (abs(x[i]) + abs(y[i]))

@the-r3aper7 I suggest working on a different issue first. Implementing this feature will likely be more involved, as requires some understanding of our strided array machinery.

ok

will it be okay if i learn it first then come to this?
