laytyp is returned as "NoneType" in MP7.py for structured grids in 3.2.12

[TroelsNV]

MP7.py:
Line 331: return np.array(laytyp, dtype=np.int32)

Issue:
The laytyp returns NoneType since the laytyp is assigned to the package object and not the base modflow object.

e.g. "upw.laytyp" returns a Util2D array, but mf.laytyp returns None (here upw is the name of a ModflowUPW object and mf is a Modflow object)

@TroelsNV, I'll take a look at this issue this afternoon.

@TroelsNV, can you supply more information or your script that you are working with. I'm unable to reproduce this error with my simple test case.

The BaseModel class (base for Modflow and Modpath7) calls the UPW file to get laytyp and in my case seems to be functioning appropriately.

@jlarsen-usgs , thanks for looking at this. I have made a small test model that produces the error.
