Palette 2 Filament Buffer Runout Switch

Many prints failed on my Mosaic Palette 2S as the Filament Buffer inside is to small, if I print over [63mm/s in average]([https://www.youtube.com/watch?v=8NZ-QnqrD3U&t=534s) between two sclices. Sometimes a splice happens directly after an pong which would drain the buffer completely.

Using the Parameter "Enable Print Speed Control During Splices:" inside the Pallete 2 OctoPrint plugin might help if you are willing to slow down the speed.

I've been quite happy with my Palette 2 on smaller, detailed prints with a lot of color changes. Bigger Prints with small as [this one sized on 250%](https://www.thingiverse.com/thing:2350630) failed for me many times during this issue.

There are other options to prevent this issue as adding an [external filament buffer](https://www.thingiverse.com/thing:3548274), but I was not willing to print this huge thing which did not fit on my Printer/Palette configuration.
