Modify lightfield encoding example
Modified the lightfield encoding example to accommodate HW implementation
requirements. Fixed the encoding scheme, generated a bitstream of a list
of references followed by the surrounding large scale tile coded frames.
All large scale tile coded frames use the same uncompressed frame header
and the same set of frame contexts. This example also wrote out the frame
header and frame contexts while encoding a large scale tile frame and
setting EXT_TILE_DEBUG to 1.
