01f6df01b6 go2meeting: disallow tile dimensions that are not multiple of 16
Original decoder seems to always use 176x128 tiles anyway and this helps
avoiding lots of issues with odd tile sizes in fuzzed files.

e07ac727c1 avcodec/g2meet: Fix framebuf size
Currently the code can in some cases draw tiles that hang outside the
allocated buffer. This patch increases the buffer size to avoid out
of array accesses. An alternative would be to fail if such tiles are
encountered.
I do not know if any valid files use such hanging tiles.
