[Fluffyalien1422]

add two script events:

• fluffyalien_energisticscore:update_block_network - calls MachineNetwork.get(block)?.destroy() using the block that called the script event
• fluffyalien_energisticscore:update_block_adjacent_networks - calls MachineNetwork.updateAdjacent(block) using the block that called the script event

and add functions to call these in the public API
