The btcsuite/fastsha256 registers itself in the crypto package of
golang as a replacement for sha256. This causes problems in TLS1.3
connections that require the hash implementations to be serializable
and results in the
tls: internal error: failed to clone hash
error.By removing all uses of the library we fix that error which appears to
occur for REST connections from modern browsers that support TLS1.3.
