LoRaPHY is the abstract class for the LoRa PHY layer which governs
the LoRaRadio and provides some common functionality to all regional
implementations.
We support 10 regions and every region comes loaded with default parameters.
These parameters can be changed by the Mac layer or explicitely by the stack
controller layer using APIs provided. This layer in essence detaches Mac completely
from PHY and provides more modular approach to the entire system.
Apart from class structure, the internal functionality is directly deduced from
semtech reference implementation that's why most of the internal data structures are
used on 'as is' basis.
In addition to that, the PHY layer provides APIs to control the LoRaRadio layer, i.e.,
the lora radio driver, ensuring that the radio is accessed from a single entry point.
A seperate data structure file is added which is common to PHY layers only.
