Provide Sample Data (for Data Ingestion etc.)

[michaelweinold]

...with the merge of https://github.com/sustainableaviation/EcoPyLot/pull/15 and https://github.com/sustainableaviation/EcoPyLot/pull/18, the basics of the data ingestions pipeline are in place. All publicfunctions are documented on the readthedocs.org page. Private functions are documented using extensive docstrings.

Please provide a sample Excel sheet (along the lines of the Carculator-derived dev/other/Input data_bus.xlsx.

This will help me write unit/integration test further down the line.

It would be ideal if the file contained enough information to complete a simple calculation for a basic (fossil-fuel-driven?) aircraft.
