take_webcam_snapshot() should accept a string as parameter

[bchanudet]

Hello there,

I'm the author of the OctoRant plugin, a plugin that sends messages from OctoPrint to Discord using Webhooks.

A user has reported a bug where OctoRant is not sending any message when used in combination with MultiCam.

After investigation the crash happens when my plugin calls take_webcam_snapshot(). According to the docs, I call take_webcam_snapshot() with a string containing the webcam's name, but your plugin seems to expect a complete Webcam object, according to __init__.py:159.

Looking further it seems that even OctoPrint's own timelapse plugin is sending a full Webcam object, yet at some other places it sends only the name. Maybe I'll raise an issue on their side too.

Given the doubts raised by reading OctoPrint source code about the usage of take_webcam_snapshot(), I've asked about it on the Discord server, I'll report back here when I have an answer.
