Variable RelaySync`Const`

RelaySync: {
    Initialized: LorawanRelaySync;
    Synchronized: LorawanRelaySync;
    Unsynchronized: LorawanRelaySync;
} = ...

What an end device knows of its relay's scans, TS011-1.0.1 section 3.9.

ReadonlyInitialized: LorawanRelaySync

Nothing: no WOR frame has gone out yet.
ReadonlySynchronized: LorawanRelaySync

It knows when the relay scans, so a short preamble reaches it.
ReadonlyUnsynchronized: LorawanRelaySync

One went out unanswered, so the next preamble spans a whole scan period.
