BIDS allows several wire formats for electrophysiology raw data (BrainVision .vhdr triplets and .edf are by far the most common for iEEG; .set and .nwb are also permitted). BIDSLIB::AbstractFormatReader is the polymorphic interface every concrete reader implements so BIDSLIB::BidsRawData can drive them uniformly: open parses the format-specific header, getInfo emits a populated FIFFLIB::FiffInfo, readRawSegment returns a calibrated (n_channels × n_samples) matrix in physical units, and toFiffRawData assembles the whole recording into a FIFFLIB::FiffRawData ready to hand to MNE-CPP's filtering / source-localisation stack. formatName and supportsExtension power the dispatch implemented by BIDSLIB::BidsRawData::createReader.

Ownership is via UPtr (std::unique_ptr) because the concrete readers keep the underlying file open for lazy segment reads.
