func SyncSafeToInt(data []byte) int

A sync safe integer is an integer represented in 4 bytes of data where the leading byte is always 0. This means that in 32 bits you can represent at most a 28 bit integer. The reason for this is because in the mp3 spec, 11 1-bits in a row indicate a synchronization point. Therefore, metadata must never have 11 1-bits in a row.
