Honk: A generic webhook processor and notifier

Hey folks,

A while ago I've started working on `Honk` primarily to aid me in my day to day work. Started small, notifying of the pull requests I am interested in, then moved onto Github discussions and failed CI checks.

There are a few tools out there that do this already, but they have typically been either: - a) restricted to Github - b) outside the budget for a company that is trying to become profitable - c) generally lacked enough expressivity to highlight the cases I was interested in, or allow for any sort of generic webhook to be processed

So, the goose made an appearance. I know, it's still Github only, but all in all, it's work in progress. The aim is for this to offer a series of integrations across different services, as well as custom webhooks that developers would be interested in, perhaps from your own service as well.

I'm currently hoping to get some feedback and feature requests, so if anyone thinks they might find this helpful and would like to trial it out for a little while (currently undefined as a period, as I haven't quite implemented payments yet).

A bit more information can be found on the [about page](https://oneroar.io/about), but I am also keen to discuss this on the thread.
