Cura 5.4 "Unable to Slice" error due to missing minimum speed (3D45, 3D40) #102

Using the plugin's default settings and Dremel PLA (0.75kg) after upgrading to Cura 5.4 I get the following error:

It appears that the minimum speed is set to 0.0 mm/sec

Changing it to a nonzero value (i.e. 5 mm/sec) allows the slicing to occurr

This should be a relatively easy fix by adding the minimum speed override to the defaults (not sure if it's in the material settings or the printer defs...will investigate this in a bit and post more info & possibly a Pull request)

FWIW - the problem doesn't happen with the 3D20 where the minimum speed defaults to 10mm/sec

It appears that the cool_min_speed variable is set to zero for most of the materials for the 3D40 & 3D45 https://github.com/search?q=repo%3Ametalman3797%2FCura-Dremel-Printer-Plugin+cool_min_speed&type=code

however the 3D20 sets the cool_min_speed to 10: https://github.com/metalman3797/Cura-Dremel-Printer-Plugin/blob/49f8345a8950ee9f0dd53d319e2750c24c2288d1/resources/quality/dremel_3d20/Dremel_3D20_low.inst.cfg#L18
