What spool data do we need?

• Spool name
• Material
• Diameter
• Colorname
• Used length
• Vendor

For cost calculation we need additionaly

• Spool cost
• Spool weight
• Density

Additional Attributes delivered from other plugins

• Nozzel/Bed Temperatures
• total Layercount
• (thumbnail)

How can we get this?

• 3rd party plugin like https://github.com/NilsRo/OctoPrint-SlicerEstimator#custom-metadata
• Parse the gcode by our own

Possible GCode-Comment format

SlicerEstimator

;Slicer info:material_brand;{material_brand}
;Slicer info:material_name;{material_name}
...

Suggestion see #58

In the gcode, it looks like this:

Eight different types is an extreme example; however this might occur across the field from time to time. It might make sense knowing this beforehand. ETA: possibly related to #13 as the filament change is done via 'tool change' and thus the M600 command.

ETA: take note, the filament_vendor entry seems to not take note at all in PrusaSlicer.

Suggestion see #104

A quick test shows me that repeating output is for next item:
This is output from a two-extruder job:

; filament used = 761.8mm (1.8cm3)
; filament used = 2.2g
; filament cost = 0.5
; filament used = 73.9mm (0.2cm3)
; filament used = 0.2g
; filament cost = 0.0
; total filament cost = 0.6

hmmm...what format should be implemented and what slicer will be supported or which feature-options do we have in the slicer
