Speed up - use little endian format as default encoding about binc HOT 2 CLOSED

I looked into this before, for a long time, trying to see whether the endian-ness of a cpu has any effect on these binary encodings.

What I discovered is that they have no bearing.

Cap'n'proto is unique, in that they try to build an encoding where the in-memory representation is exactly like what the typical struct in-memory representation looks like (with padding, offsets, etc).

Encodings like msgpack, binc, protocol buffers, etc instead try to encode things using a minimum amount of bytes while still being performant/efficient. This means that the endian representation of integers by a CPU will typically have no influence on the performance of the encoding. Integers are encoded as part of a bigger structure and the CPU does not know that we are encoding integers, as the codec library (in software) just does byte array manipulation and modification.

If it has no bearing in terms of CPU cycles, then it is fine.
