Support ASN.1 BER-TLV data format

[jogerj]

@PrimitiveTag(0x61)
record Parent(Child one, Child two) {
}

@Tlv(0x62)
record Child(
    // implicit 4 byte integer
    int subone, 
    @OctetString String subtwo
) {}

final var example = new Parent(new Child(1, "Foo"), new Child(2, "Bar");
objectMapper.writeValueAsString(example); // 61 62 08020101 0403466F6F 62 08020102 0403426172

Above example is a rough idea of an implementation. Since DER and CER rules are subsets of BER, implementing BER-TLV rules is the most comprehensive way to approach this.

Is this a request for an official module extension for those formats?

You can easily create your own module extension for Jackson, as there are IMO quite a lot of extension APIs.

Fwtw, if a viable format backend was contributed, it could (eventually) be added in jackson-dataformats-binary (for 3.x, I think). Techically backends are not modules, fwtw, but extend TokenStreamFactory and JsonParser/JsonGenerator (and with 3.x, ObjectMapper as well).
