#encoding/asn1DER TLV; INTEGER fits in i64.
const class_universalpub const class_universal = 0DER subset aligned with `encoding/asn1` Marshal/Unmarshal of primitive values. No reflect: a Value is one TLV (tag + content) SEQUENCE is walked with Decoder.next. INTEGER fits i64. as_octet / as_utf8 / as_null / as_bit_string match the marshal_* tags. Value `0`.
