[RFC]: Bray-Curtis distance between two strided arrays

### Description

This RFC proposes adding a function to calculate the Bray-Curtis distance between two strided arrays.

Package: `@stdlib/math/strided/distances/braycurtis`

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

- N: Number of elements
- x: First array
- strideX: Stride for the first array
- y: Second array
- strideY: Stride for the second array

The function should return the Bray-Curtis distance between the two arrays. It is calculated by

```
d = sum( |x_i - y_i| ) / sum( |x_i + y_i| )
```

where `x_i` and `y_i` are corresponding elements from the two arrays.
