Logs have no standardize network endianess format

[jkilpatr]

Logs from BitEndian targets will be viewed as corrupt by LittleEndian decoders and vice versa. There's no standardized endianness in the serialization process.

This is further confused by the fact that we're sending over a vector of u8's so whatever issue we're having has more to do with the internals of lz4, does it write in 64 bit words? if so we may need to flip at that level, if it does also handle bytes we're looking at a more insidious internal representation issue.
