clip calls wrong clip function

[kai-tub]

Hey all.

I am loving the work on this project!
I've stumbled upon a bug and wanted you to let you know about it.
I don't know if it is actually worth "fixing".
If one calls .clip on a geopandas dask dataframe object, the dask clip function (clipping values between min/max is called)

To reproduce:

import geopandas
import dask_geopandas

path_to_data = geopandas.datasets.get_path("nybb")
gdf = geopandas.read_file(path_to_data)
ddf = dask_geopandas.from_geopandas(gdf, npartitions=2)
ddf.clip(gdf.geometry[0])

Hi, this is not a bug strictly speaking. But it is surely something worth fixing. We have introduced clip as a method on geopandas in the last release and this API change has not propagated to dask-geopandas yet. The same applies to sjoin and overlay, in fact.

We should expose sjoin and clip as methods here as well, it just hasn't been done yet.

I see.
I am quite interested in the development of the package and would like to contribute a bit if possible.
I have some experience with Dask and use Geopandas, but am not too familiar with the internals.
Maybe some issues could be marked as Good first issue?

I know this is an alpha level library, but maybe there are some small tasks I can help out with :)

@kai-tub Sorry for a slow response!

Any help is welcome, I am just not sure if there's a lot good first issues at the moment. One that comes to my mind is mentioned in #130:

covers and covered_by are 2 missing predicates that should be trivial to add here
