Determine source of sequenced_samples header line and if it should be retired/maintained

[callachennault]

Done Condition (What do we need? Why do we need it? Keep this is small as possible!)

We think that the sequenced_samples header is too large - includes all samples in the masterlist and potentially not all samples that we have in our data. Determine what the sequenced_samples header represents/where it's coming from (masterlist?), if it should be modified, or if we want to remove it from our files
