Optimise Steganography API

[ShaunR]

Hi all.

A bit of nerdy fun if you can spare some brain cycles.

I've written a Steganography API (0.9.0) and will be putting it on my site under a BSD-3 licence. It currently only uses the LSB method but I may do others if there is interest.

I've optimised it as much as I can but I expect that better people than I can improve it's performance. So. The task is to make it as fast as possible.

There is a benchmark with some images included so we can do comparative benchmarks. I'm looking forward to some innovative improvements. The winner gets a mention in the readme under SALUTATIONS.

If you can find the time and/or inclination then please post your times for the vanilla installation and then after any improvements as shown below.

Times to beat so far:

LabVIEW 2009 x64, Win10

Before Modification:
Encode: 297.9 ms
Decode: 98.1 ms

After Modification:
Encode: 297.9 ms
Decode: 98.1 ms

Oh yes. And finally. If you find any bugs, let me know and I'll fix them.
