cast coordinates to integers

[nukappa]

probably in the merge_pAi function, some numbers have to be cast into integers

looks fine, was probably a matter of different annotation versions. a unit test has to be written to show that everything works ok.

It seems there might still be a bug here: #64 (comment)

Once 021f7ec is merged to master, I'll merge it into new_tests to see if this issue is finally resolved.

ok cool. I will test and merge #72 now.
related to the current issue, in one of your next pushes you can also improve the code in the merge_pAi_and_utr_intervals function: cast all start_position and end_position to integers: int(start_position). I wouldn't open a new pull request just for that. For now, even if it compares strings, i think it's doing it fine...

I'll changed this issue's title & labels so we won't forget about that.
