Add an example with "real world" data showing how to align grids

Is your feature request related to a problem? Please describe.
python-cmethods looks very promising, but I am struggling to get it to work on realworld data. The challenge is that I have data from HadGEM2 (360 day calendar) that I am trying to bias correct against ERA5 (standard gregorian calendar), with different spatial grids. The examples that are presented are with "toy data" and therefore don't face these issues.

Describe the solution you'd like
Are you able to extend the examples to include data where there are mismatches in the calendars and grids please?

Additional context
Partly inspired by the conversations that @ShingiNangombe and I have been having with you here: Klimaatlas/KAPy#58

Hello @markpayneatwork, unfortunately I can't DM you via ResearchGate. Could you please contact me, so that we can elaborate a proper distribution channel for the data sets?
