Nico Weber df79a2720b WebP/Lossy+Alpha: Implement filtering_method for ALPH chunk 
The spec says "Decoders are not required to use this information in any
specified way" about this field, but that's probably a typo and belongs
in the previous section. At least, images in the wild look wrong
without this, for example
https://fjord.dropboxstatic.com/warp/conversion/dropbox/warp/en-us/dropbox/Integrations_4@2x.png?id=ce8269af-ef1a-460a-8199-65af3dd978a3&output_type=webp

Implementation-wise, this now copies both uncompressed and compressed
data to yet another buffer for processing the alpha, then does
filtering on that buffer, and then copies the filtered alpha data
into the final image. (The RGB data comes from a lossy webp.)
This is a bit wasteful and we could probably manage without that
local copy, but that'd make the code more convoluted, so this is
good enough for now, at least until we've added tests for this case.

No test, because I haven't yet found out how to create images in this
format.
