Basically a generic version of the network delete method you have already:
DELETE /v1/networks/{networkId}/views/{viewId}/network/{visualProperty}/bypass
Replacing network with {objectType}. I would like to use this to remove all bypasses for nodes and edges, for example. This is needed for basic operations like unhideAll(), which currently must DELETE for each node (very slow) or toggle the bypass value (which will continue to override any mappings).
