ScatterSub

Subtracts sparse updates to a variable reference.

# Scalar indices
     ref[indices, ...] -= updates[...]
 
     # Vector indices (for each i)
     ref[indices[i], ...] -= updates[i, ...]
 
     # High rank indices (for each i, ..., j)
     ref[indices[i, ..., j], ...] -= updates[i, ..., j, ...]
 

This operation outputs `ref` after the update is done. This makes it easier to chain operations that need to use the reset value.

Duplicate entries are handled correctly: if multiple `indices` reference the same location, their (negated) contributions add.

Requires `updates.shape = indices.shape + ref.shape[1:]` or `updates.shape = []`.
