FEAT: Importing multiplexed paired-end data with separated barcode sequence files

[Keegan-Evans]

Addition Description
Adds the functionality found in extract_barcodes.py from QIIME to qiime tools [import?].

Current Behavior
There currently is not way to import multiplexed data with separate barcodes in QIIME 2, though there was a script to do so for the original QIIME.

Proposed Behavior
Adding built in functionality to support: https://forum.qiime2.org/t/importing-multiplexed-paired-end-data-with-separated-barcode-sequence-files/1469 , that is the functionality provided to the original QIIME by extract_barcodes.py.

Questions

1. Is this worth doing still at this point. Came up again on the forum on 03/21/2023 https://forum.qiime2.org/t/import-multiplexed-data/25848/5
