Reading 7 bits as an unsigned int can't result in a value exceeding 127.

Fix Theora decoding bug if loopfilter is completely disabled

Bug caused by the fact that get_bits(gb, 0) is undefined.
Doesn't affect any streams generated by the official Theora encoder, but such
streams are nevertheless valid.
Fixes decoding of CELT-933dd833-nmr-bandt.ogv.

This increases the slice size to 64 pixels, due to having to decode an
entire chroma superblock row per slice.
This can be up to 6% slower depending on clip and CPU, but is necessary
for future optimizations that gain significantly more than was lost.
