feat: add epiphan pearl driver

I need a Recording driver for the Epiphan Pearl-2 and Pearl Mini. I believe they both share the same API
https://epiphan-video.github.io/pearl_api_swagger_ui/

These devices are connected to Epiphan Cloud
the key functions needed are Starting and stopping recordings programmatically
By leveraging this API, you can remotely control recordings – for example, starting and stopping lecture captures
The Pearl REST API provides endpoints to list “recorders” (recording channels) and control them. Each recording channel or recorder has an ID - these channels typically represent a room (one device may be shared between multiple physical meeting rooms / lecture spaces)
The Pearl API also allows control of live streaming in a similar manner (via /api/channels/<id>/publishers/control/start for streams)
We should implement functions to configure Automatic File Upload - although the devices may already be configured to upload to Epiphan Cloud
We should poll the device for status, like active recordings and available local storage space remaining
