/**
 * Extends the functionality of {@link Object.assign} with the
 * ability to merge arbitrary-depth objects.
 *
 * For each key in `src` with path `k` (recursively)
 * performs an `Object.assign(dst['k'], src['k'])` with a slight change from the
 * typical handling of `undefined` for `dst['k']`:
 * instead of raising an error, `dst['k']` is auto-initialized to `{}` and
 * effectively merged with `src['k']`
 *
 * Additionally, dissimilar types will not clobber. Example:
 *
 * ```
 * const config_0 = { foo: { bar: 'bar' }, bar: 'foo' };
 * const config_1 = { foo: 'foo', bar: 'bar' };
 * const result = assignWithDepth(config_0, config_1);
 * console.log(result);
 * //-> result: { foo: { bar: 'bar' }, bar: 'bar' }
 * ```
 *
 * Traditional {@link Object.assign} would have clobbered `foo` in `config_0` with `foo` in `config_1`.
 * If `src` is a destructured array of objects and `dst` is not an array,
 * `assignWithDepth` will apply each element of `src` to `dst` in order.
 *
 * @param dst - The destination of the merge
 * @param src - The source object(s) to merge into destination
 * @param config -
 * * depth: depth to traverse within src and dst for merging
