Exception when dielectric layer is locked

[duddie]

The exception happens when dielectric layer is locked:

Traceback (most recent call last):

File "/Users/duddie/Documents/KiCad/8.0/3rdparty/plugins/com_github_30350n_pcb2blender/__init__.py", line 24, in Run

stackup.thickness_mm = sum(float(match.group(1)) for match in matches)

ValueError: could not convert string to float: '1.51 locked'

This is caused by enabling dielectric lock in Board Setup:

By clicking the check box in the PADLOCK column.

And this adds in the .kicad_pcb the 'locked' in the thickness board.

(layer "dielectric 1"
				(type "core")
				(color "#202020FF")
				(thickness 1.51 locked)
				(material "FR4")
				(epsilon_r 4.5)
				(loss_tangent 0.02)
			)

Unlocking dielectric makes the plugin works perfect.

Thanks a lot for the detailed report, this should be fixed in the next release.
