Checkqc

The `UndeterminedPercentageHandler` will now take the amount of PhiX on the lane into account. The reason for this is that all PhiX will count as undetermined indexes. This will cause runfolders for which a user may not want an error to count as one, especially since the amount of PhiX spiked in can vary a lot. The configuration thresholds in the configuration are now specified as: `<% PhiX> + <configuration value>`

Bugfixes:
- Updated interop dependency for iSeq support
- iSeq support is now mentioned in README and docs

Major changes:

New definition of reads per sample
Reads per sample are now counted per `sample name` instead of `sample ID`. It allows a sample to have multiple libraries in the same lane and still be counted as one sample. For example, in a run with the following sample sheet:

Sample_ID,Sample_Name
Pool1_1,Pool1
Pool1_2,Pool1
Pool2_1,Pool2
Pool2_2,Pool2

the sum of reads for **Pool1_1** and **Pool1_2** will be defined as the reads for **Pool1**. This was not the case in previous versions of CheckQC, where each unique `sample ID` was considered a sample.

Minor changes:
- Support for iSeq
- Improved error handling
