Incorrect way of initializing xarray.DataArray

[VasLem]

This line updates the coords variable with a value that breaks the indexing of the DataArray.

The problem can easily be replicated by running the tutorial

The error raised is:

Traceback (most recent call last):

  File "C:\Users\user\.conda\envs\triseq\lib\site-packages\xarray\core\dataarray.py", line 417, in __init__

xarray version 0.21.1 seems compatible with the current code. Maybe it should be explicitly stated in the requirements.txt, until an update to the code is composed.
