Function cbor

cbor(value: CborInput): Cbor
Convert any supported value to its CBOR representation - the single polymorphic constructor.

Custom types participate by implementing ToCbor (toCbor(): Cbor - the toJSON precedent). Tagged values are built with taggedValue.
Parameters
- value: CborInput
Returns Cbor
Example
```
cbor(42);                          // integer
cbor("héllo");                     // NFC-normalized text
cbor([1, "two", true, null]);      // array
cbor(new Map([["k", 1]]));         // map (canonical key order)
cbor({ name: "Alice", age: 30 });  // plain object -> map
```
Throws
OutOfRange - bigint outside [-(2^64), 2^64 - 1].
Throws
Custom - unsupported input type, or one of the two directive errors below.

Directive errors

Two input shapes throw a directive CborError because encoding them silently would produce ambiguous or divergent bytes:
- plain objects shaped exactly {tag, value}: use taggedValue(tag, content) for a tagged value, or add/rename a key for a map;
- objects implementing taggedCbor() but not toCbor(): add toCbor() { return this.taggedCbor(); }.
