convert_fendl script broken

[makeclean]

As in #5 CI mayve stopped this, but it seems that convert_fendl is broken - I get this error

Traceback (most recent call last):
  File "convert_fendl.py", line 87, in <module>
    downloaded_file = download(url, context=ssl._create_unverified_context())

@shimwell any ideas?

Looks like IAEA changed something in their configuration such that the download needs to appear as though it's coming from a browser. Unfortunately, that's not something that normal CI would have caught (unless we were running nightly tests or something). Anyway, I'll put in a fix (this requires something extra in OpenMC's download function).

[makeclean]

Thats my point, maybe we should be running nightly tests that tries to build and get all the data, each one as a different element in the matrix?

Interesting, I didn't think this was possible with Travis but evidently it is. The problem we'll run into is that the "generate" scripts actually run NJOY for all evaluations which takes a long time (longer than the Travis job time limits).

This was fixed by #7.
