This is my first time contributing to the project so I am not certain the structure or approach is the best. Please let me know if there is a better way to implement this. This also includes two other changes. First, it drops some code for backwards-compatibility with numpy 1.12, which isn't supported. This code was hiding an error I needed to have access to in order to get the function working. Second, it adds an option to `Dataset.map` to let you map `DataArray` methods by name. I used this to implement the `Dataset` versions of `idxmax` and `idxmin`. - [X] Closes #60 - [X] Tests added - [X] Passes `isort -rc . && black . && mypy . && flake8` - [X] Fully documented, including `whats-new.rst` for all changes and `api.rst` for new API ","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/3871/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,,13221727,pull
