Add xarray #80

It would be nice to have https://github.com/pydata/xarray on Carnets. I tried to install with !pip install xarray but I got the following error (sorry for the funky formatting):

It should be able to install, since scipy is an optional dependency. I've added it to the the list. https://github.com/holzschu/Carnets/projects/1

So, I checked and tried.

The current version of xarray requires a pandas with version >= 0.25, and Carnets has version 0.24.2. So pip tries to install the latest pandas version, and fails because it cannot compile it.

You can force pip to install the previous version with !pip install xarray==0.14.1 (that is the version of November 19, 2019, instead of January 30, 2020).

You can also force pip to install the latest version of xarray with !pip install xarray --no-dependencies, but I do not recommend it.

Hi, "%pip install xarray" now works with the latest TestFlight version (soon to be the AppStore version).
