Canals connecting indirect return points to salmonid rearing streams

Supplementary `sf` geometry layer containing the non-salmonid rearing streams and canals used to calculate the flow distances from indirect return points to their nearest salmonid rearing stream (in the `ds_fbs_dist` attribute of `returns`)
