Non-intrusive Jupyter integration

[xbwwj]

Currently, Deno's Jupyter integration is defined as a [Symbol.for("Jupyter.display")] method on object.

There are concerns (apache/arrow-js#296 (comment)) that this may increase code size, since it's hard to tree-shake class methods.

Is it possible to do Jupyter integration in a more non-intrusive, tree-shaking friendly way?

A naive thought is to use a separate extension module:

// table.extension.ts
Class.prototype[Symbol.for("Jupyter.display")] = ...

But this is definitely a bad practice in TypeScript.
