Template Errors for Primes Less than 256 bit #21

Closed actuallyachraf closed 4 years ago

actuallyachraf commented 4 years ago

When generating prime fields for primes less than 256 bit (128-bit or 192-bit) a template error (out of range index for slice) is returned at line 61:16 .

Just fixed that (https://github.com/ConsenSys/goff/commit/6a33dccb1448e44f5d94a1b2360207c281a43ee8) ; please update to goff v0.3.0 :-)
