INVLIB::InvHpiModelParameters captures the four quantities that fully determine the design of the sinusoidal HPI signal model: the list of HPI coil drive frequencies (typically four MEGIN / Elekta coils between 154 and 304 Hz), the sampling frequency of the acquisition, the local power-line frequency (50 / 60 Hz) and a bBasic flag that selects whether the line component is included in the regressor matrix. Value-typed with copy semantics and equality operators so the cache logic in InvHpiDataUpdater and InvSignalModel can detect changes cheaply.
