Fail to parse FQ cards

[dodu94]

Describe the bug

It seems that montepy is not able to parse correctly FQ cards

To Reproduce

problem = montepy.read_input("foo.imcnp")

Error Message (if any)

Traceback (most recent call last):

Thanks @dodu94. This doesn't surprise me with how FQ syntax is. This should be tackled with #11.

Though a stop gap measure is probably a good idea.

[dodu94]

I quickly went through #11 and, if I understand correctly, that is about having a full support of tallies. I support that, but in the meantime I guess montepy should just recognize FQ simply as a data card without knowing what it is exactly and just go on with the parsing right?

[MicahGale]

Yes. It's just that we don't have a rule for a data input that is all text right now. So yes we'll do a stop gap measure to just make it parsable and not error out.
