TypeErrors using Deno

[dnicolson]

Running the following script results in type errors when using Deno:

echo 'import plist from "https://cdn.skypack.dev/[email protected]?dts"' | deno run -

https://github.com/wollardj/simple-plist/pull/65 can potentially fix some of them.

I just started using Deno for another project of mine and this exact issue crossed my mind. I'll target https://deno.land/x support for the next release.

I couldn't quite get skypack to work for me, but esm.sh with v1.4.0 works. Granted I don't know much about either service, but it seems like esm.sh is automatically injecting the node compatibility bits from deno.
