ChannelDataModel keeps a per-channel Eigen::MatrixXd ring buffer of the most recent N seconds of data and translates Qt's QAbstractTableModel API into the view-friendly per-row / per-time slice access that ChannelDataView and RtFiffRawViewDelegate need. It also tracks bad-channel flags, trigger annotations and the currently-active SSP / compensation / filter operators so the delegate can render the pre-processed signal without touching the raw buffer.
