270 change check raster grids to take in raster profiles instead of raster data

[msorvoja]

Function check_raster_grids in eis_toolkit/utilities/checks/raster.py takes in a sequence of raster profiles instead of raster data now. Tests and some dependent functions were modified, see list edited modules below.

Edited modules:

eis_toolkit/utilities/checks/raster.py
tests/checks/check_raster_grids_test.py
eis_toolkit/raster_processing/unique_combinations.py
eis_toolkit/utilities/checks/crs.py
eis_toolkit/cli.py

Deleted modules (check_raster_grids.py was a duplicate):

docs/raster_processing/check_raster_grids.md
eis_toolkit/raster_processing/check_raster_grids.py

Just a few small things, otherwise looking good!

I would keep the original implementation unless it didn't work. Raster profile might be missing a CRS in some cases, and this implementation will result in error in that case.

We could also move this test into the raster.py file under checks, as it's only used for rasters (and delete this crs.py file).

@nmaarnio Since raster profile (or metadata) is a dictionary, the dot notation won't work (object.crs).

How about this?
`@beartype
def check_matching_crs(objects: Iterable) -> bool:
"""Check if every object in a list has a CRS, and that they match.

Args:
    objects: A list of objects to check.

Returns:
    True if everything matches, False if not.
"""
epsg_list = []

for object in objects:
    if not isinstance(object, (rasterio.profiles.Profile, dict)):
        if not object.crs:
            return False
        epsg = object.crs.to_epsg()
        epsg_list.append(epsg)
    else:
        if "crs" in object:
            epsg_list.append(object["crs"])
        else:
            return False

if len(set(epsg_list)) != 1:
    return False

return True`

[msorvoja]

Now it returns False if object is a profile or dict and it does not contain key "crs".

Looks good now!
