Replace barcode sequence with sample-Id

The manifest format is only for already demultiplexed data. It really sounds like your reads aren’t demultiplexed, but if you could confirm one way or the other, that would be great. If they aren’t demultiplexed, we should be able to import as MultiplexedPairedEndBarcodeInSequence, and follow along with the q2-cutadapt community tutorial to demultiplex these reads.

Indeed, the reads aren't demultiplexed and I could follow the q2-cutadapt community tutorial.
However, this rises the another issue
Thanks for the help!
