Height and width set in XML have just been ignored (they were expected
as option nodes, not attributes).
This has been fixed. Please revisit your spacer sizes...

Some missing keys in the katabatic flows module have been added, some
unnecessary keys removed from MeteoIO (no need for POIs there). Some
file extensions are now specified as filters when it makes sense.

A few errors have also been fixed for Snowpack (missing the SNOW_WRITE
key and wrong type for HOAR_DENSITY_BURIED)
