// Mcoded7 — MIDI 2.0 Capability Inquiry property-exchange byte-packing.
// Packs 7 arbitrary 8-bit bytes into 8 MIDI bytes (a leading high-bit byte
// followed by seven low-7-bit bytes), so binary payloads can travel inside a
// SysEx envelope without ever setting bit 7.
//
// Reference: MIDI 2.0 / MIDI-CI v1.2 spec, "Mcoded7 Data Encoding".
