[feature request] better error messages

[braebo]

Hey! I've noticed that the TpError message can often be difficult to work with, and often doesn't tell me which input is causing the error which makes debugging more difficult.

A few ways I think it could be improved:

1. Printing the object causing the error to the console. A console.error({ controller }) would go very far. If not that, then even the name or any other identifying information would help a lot.

2. Dumping the stack in its own log so it's easier to work with.

Not sure how it would look exactly, but something like:

console.error({ controller }) // 1.
console.error(TpError.stack) // 2.
throw new Error(TpError)

As it is now, it can be cumbersome to navigate the stack trace as a string in devtools, and things like links obviously don't work. It would be nice to have the objects in the console instead of stringified versions from TpError:

These are just some ideas -- what do you think? I'd be happy to make a PR if you like any of them!
