`Info` header is used for CBR files, but in some cases not **every** frame in these files is the same size. This change stops using the single frame after the `Info` frame as the 'template' (and assuming all subsequent frames are the same size/bitrate), and instead derives the bitrate from fields in the `Info` header. This works for files which are 'almost' constant bitrate, like the one in Issue: androidx/media#1376 where every frame is either 1044 or 1045 bytes except the one immediately after the `Info` frame which is 104 bytes (32kbps), resulting in a wildly incorrect duration calculation.
