IDF import does not honor UNPLACED status

[efa]

The IDF v3.0 specification foresee 4 possible values for Placement status of parts in .emn files:
PLACED, UNPLACED, MCAD, ECAD

PLACED is for optional parts, very common on ECAD, where a component is not mounted.
As now all parts are placed also when UNPLACED is set.

For example I have a file with those lines in .PLACEMENT section:

"RM0603" "RM0603" "R148"
124.0000000 169.3000000 0.0000000 270.0000000 TOP UNPLACED

but the part is drawn on PCB like was a PLACED part.

UNPLACED parts, should be invisible, or rendered drafted like dotted, or shadowed.
