Add td.asyncFunc

[searls]

There has been some intermittent discussion of how we can make the tdjs API feel terser for async functions, and support is good enough now that I think we can solve it by adding a new top-level constructor td.asyncFunc and update imitate() to invoke that for all instances of AsyncFunction

This would resolve: #245 #371

Love the idea! 👍

I'd love to see this as well! Something to consider is that I would expect mockAsyncFn[Symbol.toStringTag] to return "AsyncFunction" to allow full interoperability with how current versions Node.js tag async functions.

async function actualFn() {}

assert.equal(actualFn[Symbol.toStringTag], "AsyncFunction")

const mockFn = td.asyncFunction("mockFn")

assert.equal(mockFn[Symbol.toStringTag], "AsyncFunction")

Stale. Closing. Please reopen if still relevant and I will look into it.
