New, faster ECC libraries

[lrq3000]

Should implement faster ECC libraries.

C/C++ fastest ECC libraries:

• FastECC - O(N*log(N))
• catid's fecal (example of implementation in https://github.com/catid/siamese)
• https://github.com/SianJhengLin/Fast-algorithms-of-Reed-Solomon-erasure-codes
• Alternatives to FastECC Bulat-Ziganshin/FastECC#4
• Wirehair - Fast O(N) LDPC algorithm
