Assemblies may not have their face information in the top level of the
file. Search recurses to get the explicit shape in sub assemblies as
well.

(cherry picked from commit a2168c6add)
This changes the IGES import parameter precision to be file-defined
instead of hard-coded in KiCad. OCE-0.18 does not handle faces with
a set of points whose approximation creates a single point.
By allowing the file to set the precision level, we leave it to the
generating program to create a file with non-degenerate faces.
