LERC codec: deal with issues with multi-band PlanarConfig=Contig and NaN values
Fixes https://github.com/OSGeo/gdal/issues/9530. Cf https://github.com/OSGeo/gdal/pull/9548 for the GDAL specific fix.
The LERC codec up-to-now didn't do any special processing when writing a strile in a multi-band PlanarConfig=Contig file, resulting in corruptions. Now we generate a mask buffer in that situation. Actually, if the NaN values are not at the same location accross bands, we need to write one mask-per-band, which requires liblerc >= 3.0, and in that situation change the LERC blob to multi-band instead of multi-depth/dim, with liblerc >= 3.0. When all bands have NaN values at the same location, we generate a single mask, which is compatible of liblerc < 3.0, but requires at last this version of libtiff to be read. This is the best solution we come with to fix the issue while having the maximum backward compatibility.
