Detailed Description

Duty-cycled receive window calculation.

A pure, side-effect-free helper that computes listen/sleep windows for duty-cycled receive from the modulation parameters and the preamble length senders use. It needs no chip and performs no I/O, so it is constexpr and the windows can be computed at compile time for a fixed link configuration.
