better structuredClone support

[jimmywarting]

I have created this page to test out how good some packages are at mimicing structuredClone and also testing out how fast and efficent they are

Maybe you want imporove the score...?

oh, very interesting! I think I can slightly improve the score with an encode option: { mapSorter: null } to override the default CBOR map sorting function; other than that the other items in the list are outside of the design goals of this library since its primary purpose is deterministic encoding forms and making novel CBOR tags pluggable (i.e. if you want Date, RegExp etc. then you bring your own tag plugin). Maybe something to work on because I export some basic tag plugins here; I just don't have the need for it.

Thanks for doing this though, perhaps I'll add a link on the README to it.

I'm just wondering how come that when running decode(encode(1n)) equals to 1 and not 1n?

[jimmywarting]

Also if i would like to add a own Blob/File tag plugin then it would have to read the file in a async manner...
is there any possibility to encode/decode things in a async manner and await a result?

everything looks pretty sync to me in this package

i think that cbor also has references support? no?

i mean this example:

var input = Array(2).fill({})
var clone = decode(encode(input))
console.assert(clone => clone !== input)
console.assert(clone => clone[0] === clone[1])
console.assert(clone => clone[0] !== input[0])

it should pass?
