@msgpack/msgpack compatibliity

[jackyzha0]

hey there, thanks for your awesome work on this library!

we're interested in switching https://github.com/replit/river from using @msgpack/msgpack to using this package instead but found a few compatibility things with serializing some specific JS values (namely preserving Uint8Array)

{
  buff: Uint8Array.from([0, 42, 100, 255]),
}

 FAIL  codec/codec.test.ts > codec -- 'binary' > example -- 'buffer test' > encodes and decodes correctly
AssertionError: expected { buff: Buffer[ 0, 42, 100, 255 ] } to strictly equal { …(1) }

- Expected
+ Received

  {
-   "buff": Uint8Array [
+   "buff": {
+     "data": [
        0,
        42,
        100,
        255,
      ],
+     "type": "Buffer",
+   },
  }

with the test pretty much being packr.unpack(packr.pack(<payload>)) we were wondering if it was possible to add a compatibility flag to preserve Uint8Array?
