2/2 Added vendor/ dir to lock down dependent pkg versions.
The author of git.schwanenlied.me/yawning/{chacha20,newhope,kyber}.git has copied
their repos to gitlab.com/yawning/ but some imports of chacha20 from newhope still
inconsistently refer to git.schwanenlied.me/, breaking build.
Licenses for chacha20 also changed from CC0 to AGPL, which may or may not be an
issue. Until the two aforementioned issues are resolved, locking to last-good
versions is probably the best way forward for now.
To build with vendored deps, use make VENDOR=1 clean all

Installation
To get the package use the standard:
go get github.com/templexxx/xor

Performance
Performance depends mainly on:
- SIMD extension
- unit size of worker
- hardware ( CPU RAM etc)
Example of performance on my MacBook 2014-mid(i5-4278U 2.6GHz 2 physical cores). The 16MB per shards.
speed = ( shards * size ) / cost
