With xor filters only charge delta vs entire xor filter

[jdgemm]

XOR filter transaction happens every 10 mins to start join process for devices to send packets on the network.

Each time, in addition to base txn cost (35,000 DC), there is also a charge for space on the blockchain. XOR filters are charged same each time regardless of the actual change to the filter. This increases the costs of adding devices to the network significantly.

Instead the charge for space on the blockchain should only take into account the delta or difference that gets added.
