fix(GridIntersect): fix DeprecationWarnings for Shapely2.0 (#1504)

* refactor(make-release): Software citation developed from version.py

Closes #727

* release: update mf6 v6.1.1 dfn and flopy mf6 classes (#1)

* docs(misc): clean up docstrings

* refactor(GridIntersect): fix error message
for unsupported methods

* bug(GridIntersect): fix #10
ensure one entry per grid cell in polygon intersection result
add test for this case

* bug(gridintersect): fixes #917

bug in structured mode where linestrings were not handled
correctly if they pass in and out of grid cell

* fix(GridIntersect): #1035
- fix vertices when intersecting linestring with offset grids

* fix shapely2.0 deprecation warnings
- keep separate lists of cellids and geometries
- use .geoms for iteration over multipart geoms
- add deprecation warnings to old methods to generate list of geoms
- update intersect_* methods to use new STRtree api
- update tests
- add replacement function for deprecated descartes PolygonPatch

* update notebook

* run black, isort, docformatter

* update to new STRtree implementation
filter shapely2 warnings
add shapely<1.8 exception
update shapely warning filtering since shapely>1.8 required

* address @jlarsen-usgs review comments

* quick fix to get_lrc call

Changed
```python
mfgrid.get_lrc([node])[1:]
```
to
```python
mfgrid.get_lrc([node])[0][1:]
```

* change list to tuple in get_node()
