------------------

- Bugfix: `half verhard` instead of `half_verhard` (without underscore).

- Include cross section information for weirs and orifices.

- Better error message when v2_connected_points are outside 2D grid domain.

- 2D grid cannot contain uneven number of pixels in one grid cell.

- Bugfix in grid.sort() for models with no flowlines.

------------------

- Use the bank_level for 1D2D lines to connection nodes without manhole but with
storage area.

------------------

- Fixed extracting EPSG code from outdated CRS WKT definitions.

------------------

- Disable tests for CI Build Wheel, because GDAL is not included on build machine.

------------------

- Write the WKT of the CRS (in addition to the epsg code) into the gridadmin.

- Drop rasterio as optional raster interface.

- Append / prepend coordinates to channel/culvert linestrings if they do not intersect
the connection nodes they are attached to.

- Only give node_type 4 and kcu 52/54 to manholes with a not-NULL storage area.

- Use pygoes to calculate grid refinements.

------------------

- Store epsg_code as string in GridMeta.
