AppEUI only XOR Filter Entries

[michaeldjeffrey]

An XOR filters contents is the hash of a (app_eui, dev_eui) pair. This means every device that added to an OUI needs to squat on a shared EUI pair and have a unique app_key (highly not recommended), or make a new EUI pair and wait the amount of time it takes to add into an XOR filter and propogate the block with the update through the network.

An alternative solution is to provide a way to encode an app_eui (join_eui) into an XOR filter such that it accepts all dev_eui's matching the app_eui.
