Fields

This was based off of Roku's BIF File Specification.

Each BIF file (according to this struct) will have a Header and Images, and each field is well-documented within the KSY and the Roku specification.

Header:

• Magic
• Version
• Number of images
• Timestamp multiplier

Images (array, size is number of images in Header):

• Timestamp
• Offset
• JPEG binary data
