RSeQC tin.py module errors when providing empty input file

[drpatelh]

Description of bug

Running the rseqc/tin module errors if an empty file is found.

Tested with MultiQC v1.11

File that triggers the error

An empty file provided to the module will trigger it. I set this in the config for it to be found.
