Need to a account for headers (e.g., VCF)

What is the use case? Isn't tabix better for that?

For instance I was using grabix to check a line in a VCF when conversion to plink format failed. Plink complained about some SNP, but only gave a line number. Grabbing the line number with grabix immediatelly showed me the problematic part. As plink didn't care about header, grabix worked perfectly.

If you want to implement this, consider adding an option instead of making it default behaviour, please. And thanks for the awesome package 😉
