// Conflict detection is performed in the following way. Similar methods are used for
// hardware and software serial, but the implementations are indepenent.
//
// 1. Populate a data structure with UART parameters and addresses for all possible axis.
// If an axis is not in use, populate it with recognizable placeholder data.
// 2. For each axis in use, static_assert using a constexpr function, which counts the
// number of matching/conflicting axis. If the value is not exactly 1, fail.
