Support for iSeq, and improved org for testing

[johandahlberg]

This adds support for the Illumina iSeq, and also makes some changes to the way that the RuntypeRecognizer works by introducing a separate class for reading the files in the runfolder. This makes this easier to mock in the tests, which makes it easier to test that the correct instrument is returned depending on which type of runfolder is passed in.

The QC criteria that I have added are completely arbitrary, and need to be update.
