Empty lines in samplesheet.csv cause a crash

Description of the bug

Empty lines in samplesheet.csv (for example having a trailing newline) cause the workflow to crash. I think this seems a bit overly strict and can easily be parsed?

Thanks for reporting @holmrenser ! Fixed in drpatelh@71c0d38

There can be a blank line anywhere in the file now and it will be ignored. I think it's reasonable to be stricter with this sort of validation as in theory these lines have no information content. Surprised it has taken this long for someone to report it though! 🙂

Now that we have a samplesheet schema, the hope is that we will be able to use this to validate the contents at some point We made a start in #633 but the validation may be less flexible if we decide to use standard libs. Lets see what happens.

Take care!
