`parseSysEx` and `buildSysEx` are the canonical helpers for working with MIDI System Exclusive payloads — the manufacturer-defined byte streams that sit between an `F0` prefix and an `F7` terminator. Every vendor uses SysEx for patch dumps, parameter sysex, MMC (MIDI Machine Control), and identity-request handshakes; standardising the parse / build code in one place prevents off-by-one errors with the one-byte vs three-byte manufacturer-id forms.
`parseSysEx` expects the *body* of the frame (i.e. everything between `F0` and `F7`, exclusive of both endpoints). `buildSysEx` produces a complete `F0...F7` frame; callers feed the result straight to `MidiPortLike.send`.

## Purpose
MIDI 2.0 introduces the Universal MIDI Packet (UMP) format — fixed-width 32, 64, 96, or 128 bit packets that carry MIDI messages alongside high-resolution per-note controllers, per-note pitch, and 32-bit velocity. This module exposes the four packet types, the message-type nibble constants, and a *lossless* bridge between MIDI 1.0 messages and their UMP equivalents.
MIDI 2.0 introduces the Universal MIDI Packet (UMP) format — fixed-width 32, 64, 96, or 128 bit packets that carry MIDI messages alongside high-resolution per-note controllers, per-note pitch, and 32-bit velocity. This module exposes the four packet types, the message-type nibble constants, and a _lossless_ bridge between MIDI 1.0 messages and their UMP equivalents.
The bridge is deliberately one-way for any MIDI 2.0 feature that exceeds MIDI 1.0's expressivity: a MIDI 2.0 channel-voice packet with 32-bit velocity cannot be downgraded to MIDI 1.0 without losing precision, so `umpToMidi1` rejects it with `MidiError("MIDI.UNSUPPORTED_UMP_VARIANT")` rather than silently truncating. Engines that want to "best-effort downgrade" wrap this bridge with their own approximation policy.
