Zcrypto cannot represent the extension name Policy Constraints in JSON output

[GOODPWDCETCSZ]

Env: Ubuntu x64

Go version: 1.13, 1.15

reproduce: ./zcertificate seed-7s35-9s14-37s37-55s29-750s39.pem

Expected result: the extension policy constraints is displayed correctly in JSON output instead of unknown extension

Actual result:

"unknown_extensions": [ ... { "id": "2.5.29.36", "critical": false, "value": "MAaAAQGBAQI=" }, ... ],
