Zcrypto does not represent the 'critical' value of keyUsage and basicConstraints in JSON output

[GOODPWDCETCSZ]

Env: Ubuntu x64

Go version: 1.13, 1.15

Reproduce: ./zcertificate seed-7s35-9s14-10s18-26s21.pem

Expected result: keyUsage and basicConstraints are shown "critical": true/false

as 2.5.29.46 (Freshest CRL) is shown "critical": false.

Actual result:

"extensions": {
"key_usage": {
"certificate_sign": true,
"value": 32
},
"basic_constraints": {
"is_ca": false
},
"authority_key_id": "ead39df2fa12151d6b90011f1ddb277fafd165d7"
},
"unknown_extensions": [
{
"id": "2.5.29.46",
"critical": false,
"value": "MEswSaAVoRMwEQYDVQQDDApraW94aWEuY29tgQMHf4CiK4EHZ0BoLmNvbYIPd3d3LmV4YW1wbGUuY29thg93d3cuYi5jb20vYy5leHQ="
}
