Nico Weber c0f67a0188 LibGfx/WebPWriter: Remove a copy in the animated frame writing code path ...

This code path now also compresses to memory once, and then writes to
the output stream.

Since the animation writer has a SeekableStream, it could compress to
the stream directly and fix up offsets later. That's more complicated
though, and keeping the animated and non-animated code paths similar
seems nice. And the drawback is just temporary higher memory use, and
the used memory is smaller than the memory needed by the input bitmap.
