Fix handling of dat files

Description of bug

*.dat files have to live in the top-level jO directory (same level as the top-level jO) however this was not treated correctly in the most generic case.

Consider the following cases:

• testLuigi/Cards/param_card_SM_SVT_leplep.dat : Should be skipped
• testLuigi/param_card_SM_SVT_leplep.dat : Should be added
• 100xxx/100001/Cards/param_card_SM_SVT_leplep.dat : Should be skipped
• 100xxx/100001/param_card_SM_SVT_leplep.dat : Should be added

The bug is that the condition !($name =~ $naming/.*/.*\.dat)) evaluates to false when you have something like 100xxx/100001/param_card_SM_SVT_leplep.dat which should be accepted
