Size error with ACT DR4

Tried to run the example with ACTPol_148_D5_PA1_S1_1way_I.fits from https://lambda.gsfc.nasa.gov/product/act/actpol_maps_get.html

I get an error in the shape of the arrays:

python fits.py create ACTPol_148_D5_PA1_S1_1way_I.fits ACTPol_148_D5_PA1_S1_1w
ay_I

ValueError: could not broadcast input array from shape (667,675) into shape (674,675)

Start by running the command shown in example/fits.py with the referenced ACT DR4 FITS file. Read tilemaker/processing/fits_simple.py around create_data_from_children and the failing assignment at line 310 to trace the array shapes. Done means the example processes this input without the broadcasting error, with the intended handling of the differing shapes confirmed.
