Support Date encoding in msgpack

[tzador]

Dates are ubiquitous, would be great to be able to transfer them.

Currently dates are not supported, an error gets thrown.

Dates would get encoded/decoded just like the rest of supported datatypes.

For example:
https://www.npmjs.com/package/@msgpack/msgpack
supports encoding of dates.

If you specifically mean for msgpack, you should add it to the title for clarity.

On another note, dates are supported in @std/cbor, but I don't know if that's useful in your instance.

Thanks for noticing, updated the title.
Nice, taking a look at @std/cbor
