Node Provisioning Delete Command
This command is useful for deleting Z-Wave nodes from the node provisioning
list.
After deleting a Z-Wave node entry from the node provisioning list you will
still have run excluded the node from the Z-Wave network.
Params:
* `:seq_number` - the sequence number for the network command (required)
* `:dsk` - the DSK string of the node to delete, please see
`Grizzly.ZWave.DSK` for more information (required)
