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="
},
...
],
