Subject: [PATCH] test vector that passes in node, but fails in browser/sjcl

There is some kind of problem either in bitcore or sjcl involving the
decodeURIComponent function. I discovered this issue while working on the
network protocol for Copay.  Decrypting binary data in sjcl produces problems
due to the way sjcl is interpreting data as strings. I will have to investigate
further tomorrow. For now I am producing this test vector to demonstrate the
issue.
