Fuzz NewManifestFromReader and cap the zstd decoder (closes #65)
FuzzNewManifestFromReader fails when the parser returns both or neither
of a manifest and an error, or allocates more than a fixed multiple of
its input and the decompressed data it may read, plus room for the
decoder's window buffers. make test runs the seed corpus; make fuzz
fuzzes for one minute.

Parser bug: MaxDecompressedSize did not bound decompression; the zstd
decoder decoded a payload under 128 KiB in full before the LimitReader
read any of it. It now decodes only what the LimitReader reads and
refuses windows over the 8 MiB mfer writes with. Seeds: a frame claiming
8 GiB, two frames together over the limit, empty frames with growing
windows.
