Title: OpenSlide: convert "layer" to "level" where externally visible

OpenSlide >= 3.3.0 will use the term "level" instead of "layer". To avoid gratuitous incompatibility between libvips 7.28 and later versions, change this now in the openslideload argument, the "slide-layer" metadata item, and error messages.
