Polynomial Code for ISA-L

[GrokDarkMatter]

For those of you who may have wondered if it is possible to adapt ISA-L to Polynomial Codes, I am happy to report that the answer is yes. You can see the updated ISA-L library at github.com/GrokDarkMatter/ISA-L-PC. This source is free to download and evaluate, and demonstrates how to build, apply and use Polynomial Codes for both Erasure Coding and unknown error detection and correction.

It has an interactive tool, erasure_code_perf, which displays the Polynomial matrix, and allows the user to choose any parity size (-p val). It also demonstrates how to use Galois Field arithmetic on Syndromes to identify unknown error location and unknown error value.

I hope you enjoy exploring Polynomial Codes.

Thanks for sharing. Just a note that standard BSD 3-clause license does not include the following paragraph added by you to the license in the repo above:

In other words, this code is provided solely for the purposes of
evaluation and is not licensed or intended to be licensed or used as part of
or in connection with any commercial or non-commercial use other than evaluation
of the potential for a license from Michael H. Anderson. Neither Michael H. Anderson
nor any affiliated person grants any express or implied rights under any patents,
copyrights, trademarks, or trade secret information. No content may be copied, 
stored, or utilized in any way without express written permission.

As the result, github.com/GrokDarkMatter/ISA-L-PC is not 3-clause BSD license project.

Please leave original (i.e. Intel) copyright and license text intact and add yours on top of that. Please correct SPDX accordingly.

You are welcome. I hope you enjoy it.

Sorry about the license not being quite right, I'm not very experienced regarding BSD licenses, I will update it with the next release.

Does this look OK? If you think it's OK, I'm ready to revise and release.
