BUG: CellAligment bug with enclosed tessellation

When computing CellAlignment on enclosed tessellation, a Length mismatch error is generated. This seems to depend on the fact that enclosed tessellation, unlike "traditional" tessellation features polygons that do not contain building geometries. A way around this could be excluding empty cells or assigning NaN/0 values?

@AleFeli

Hey @AleFeli, I am not able to reproduce this. With the following code, which results in 144 buildings and 153 cells, CellAlignment works as intended. Can you send the full Traceback or find out which situation causes the failure?

import geopandas as gpd
import momepy as mm

roads = gpd.read_file(mm.datasets.get_path('bubenec'), layer='streets')
blg = gpd.read_file(mm.datasets.get_path('bubenec'), layer='buildings')

enclosures = mm.enclosures(roads, gpd.GeoSeries([roads.unary_union.convex_hull]))
et = mm.Tessellation(blg, 'uID', enclosures=enclosures)
tess = et.tessellation

ca = mm.CellAlignment(blg, tess, mm.Orientation(blg).series, mm.Orientation(tess).series, 'uID', 'uID')

No failure in this case. I will try to find out more using the data I was working with when I found the issue.
