Description

This PR adds the ability to disable Power Loss Recovery on Bambu Lab machines.

There is chatter online that the feature causes excessive wear on Micro SD storage, while the feature sounds great, I personally would rather disable it and reduce any additional wear on the storage.

I have added a tick box/toggle to the machine section, will require develop mode to be enabled and is an opt in to disable, so it shouldn't impact any existing logic unless specifically toggled to disable the feature.

Attached is a sample 3mf with the exported gcode with Power Loss Recovery enabled/disabled (as compared in the above screenshots)

To test this, you'll need to let the print run until the part fan kicks in (or around layer 3), since I think that the g-code waits until layer 2 in order to enable the Power Loss Recovery.

Example videos of the feature.

Enabled (default)
