cbor2 JavaScript implementation

[millette]

https://github.com/hildjj/cbor2

This package supersedes node-cbor, with the following goals:

• Web-first. Usable in Node and Deno.
• Simpler where possible. Remove non-core features in favor of extensibility.
• Synchronous decoding. Removes streaming capabilities that are rarely used.
• Complete break of API compatibility, allowing use of newer JavaScript constructs.
• No work-arounds for older environments.
