feat: convert to typescript (#16)

- Only named exports
- No more CJS, only ESM
- Adds auto-publish
- Adds dependabot
- Adds tests for abortable sink/source/duplex
- Removes support for multiple abort signals - just use `any-signal`

BREAKING CHANGE: switch to named exports, ESM only

-#### Parameters
-
-| Name | Type | Description |
-|------|------|-------------|
-| source | [`Iterable`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols#The_iterable_protocol)\|[`Iterator`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols#The_iterator_protocol) | The iterator or iterable object to make abortable |

-#### Returns
-
-| Type | Description |
-|------|-------------|
-| [`Iterator`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols#The_iterator_protocol) | An iterator that wraps the passed `source` parameter that makes it abortable via the passed `signal` parameters. |
-
-The returned iterator will `throw` an `AbortError` when it is aborted on _any_ one of the passed abort signals. The error object has a `type` with the value `aborted` and `code` property with the value `ABORT_ERR` by default.
