Readme example fails with keeyerror

[shimwell]

Hi IAEA

Thanks for making the repo.

I'm just taking a look and noticed the example in the readme doesn't work straight away.

I'm getting this error

Traceback (most recent call last):
  File "/home/j/exfor_json/plot.py", line 8, in <module>
    entry_data = data["003"]["data"]
                 ~~~~^^^^^^^
KeyError: '003'

Wondering if this is an easy fix for someone who knows the data structure better than me

slightly related package that might be handy

@shimwell The README has been corrected in this commit. It previously referred to an old version. and will try pytest, thanks for the suggestion!
