NAME: panel_clamp
DESCRIPTION: creates various clamps to join two panels
TODO: none
USAGE: panel_clamp(face, screw, style, dia_x, dia_y, height, mask)
face = "top","bottom","rear","front","left","right"
screw = "m2", "m2.5", "m3", "m4"
style = "sloped"
dia_x = top diameter or x size in mm
dia_y = bottom diameter or y size in mm
height = holder height in mm
mask[0] = true enables component mask
mask[1] = mask length
mask[2] = mask setback
mask[3] = mstyle "default"
