Specific exception when reading an empty file

[jeanbournhonesqueMF]

Is your feature request related to a problem? Please describe.

Greetings,

My scripts creates products for Meteo-France forecasters and I read gribs with earthkit data.

Currently in the readers/init.py file, line 221, there is a
raise Exception(f"File is empty: '{path}'")

The only way to catch this exception is a except Exception as e, which is very bad to use.

It would be way better to have a specific error class.

Describe the solution you'd like

Create a class named FileIsEmptyError (name to be specified) to be able to catch theses problems.

Describe alternatives you've considered
