/**
 * Minimal DASH SegmentBase SIDX parser. Given the raw bytes of an MP4 fragment
 * that contains a `sidx` box and the absolute byte offset at which those bytes
 * start in the remote resource, emits the list of sub-segments (byte ranges
 * and presentation times).
 *
 * Wire-compatible with iOS `DashSidxParser.swift` and Android `DashSidxParser.kt`
 * — the same input produces the same `DashSidxIndex` on all three platforms,
 * so segment IDs derived from these ranges match across the swarm.
