//! [`InstrRobSid`] — Rob-Hubbard-style C64 instrument: an
//! [`InstrSid`] voice plus the per-tick effect tables (waveform
//! cycling, pulse-width sweep, frequency arpeggio, vibrato) that
//! drove Hubbard's signature sound.
//!
//! Opaque to the xmrs sample engine: the player skips voices whose
//! `instr_type` is `InstrumentType::RobSid`. Populated by the SID
//! importer; only compiled when `import_sid` is enabled.
