//TODO change to streaming decoder
// Currently lib expects most data in memory. Due to how format is designed it's not the
// easiest thing to change, to be fixed it later:
// easiest thing to change, to be fixed later:
// - data is divided into 2 blocks (intro+body) that are decoded separatedly
// (streaming should read up to block max)
// - code data isn't divided into frames, just keeps reading from the file buf
