[Pulse] Add more integration options for service monitoring

I built Pulse to have **a quick way to see if a service is down** without opening a browser or checking Slack, mails, etc. IMO, it looks beautiful and doesn't get in the way when you don't need it. It also supports macOS notification and you can easily mute individual services. It uses a **color-coded glow around your MacBook notch: green for all clear, yellow for degraded, red for outage**. It supports **custom HTTP checks** and it integrates nicely with existing **status pages from Better Stack and Atlassian** (more are planned). I made it very easy to configure Pulse either through the settings or you can directly edit the `config.json`. You can version control the config and easily share it with your team. **No tracking, no analytics, no account. MIT licensed. Config is stored locally.** Install via Homebrew (`brew install jsattler/tap/pulse`) or download and install manually. DMG is signed and notarized. I use it for some days now and it already proofed to be useful, so I wanted to share it here. * GitHub: [https://github.com/jsattler/Pulse](https://github.com/jsattler/Pulse) * Website: [https://jsattler.github.io/Pulse](https://jsattler.github.io/Pulse) Feel free to try it out and leave a star if you like it.
