Fix cross-endian interoperability of zstd It turns out that layouts of union bitfields are a pain, and the current code results in an inconsistent layout between BE and LE systems, leading to zstd-active datasets on one erroring out on the other. Switch everyone over to the LE layout, and add compatibility code to read both.
