Detailed Description

Helper to decode format version and tsid count in formats v0, v1, v2.

/// v0:
///    tsid_count: 6 byte little-endian
///    unused: 1 byte, value 0
///    version: 1 byte, value 0
/// v1 and v2:
///    version: 1 byte, value 1 or 2
///    tsid_count: 6 byte, little-endian
///    version: 1 byte, value 1 or 2
