Add extradata files for part

[Trophime]

@remicaumette
In Case of a Helix part, we would eventually need some extra files (defined in the yaml geometry file) for 3D sims
Namely:

• files for the helix path:

** for Salome:

name + str("_cut_with_shapes_salome.dat") if m3d.with_shapes = True in yaml def
otherwise name + str("_cut_salome.dat"))

** for Catia: name+ '_cut_with_shapes.xls'
** for CAM: name + 'iso'

• and a file for shape (if shape.profile and m3d.with_shapes = True in yaml def)

How can we change the DB to reflect that?

Shall we wait to add yaml data struct for geometries as new tables in DB?
