Write Exif data block for HEIF files
Pass in Exif data block as a muxer data sample on each
image track. Add support in MPEG4Writer to write it out.
Allow grid to be used even when there is only 1 tile,
as some encoders can't encode very small images, using
grid allows them to encode in a supported size then apply
a crop to final size.
Also be more strict on esitmating the file level meta
size, since we now have to also reserve for Exif items.
