Change Description

With the current v21 release candidate, signatures that have less than 32 byte r or s values will generate signatures with lengths less than the 65 bytes necessary. The r and s need to be zero padded to resolve this issue. The elliptic library uses bn.js for the r and s values and the .toArray operation has a length argument with the purpose of zero padding the value to the length.

Fixes #663
