ENH: Add aligner property to annotate-reads-card outputs

[VinzentRisch]

The annoate-reads-card action creates outputs of type SampleData[CARDAlleleAnnotation] and SampleData[CARDGeneAnnotation].
These outputs can be used with the function kmer-analysis that is currently under development.
But the kmer-analysis can only be performed if the outputs were created with one of the three possible aligners of the annoate-reads-card function.

Because of this one of three possible properties ("kma", "bowtie2", "bwa") has to be added to the SampleData[CARDAlleleAnnotation] and SampleData[CARDGeneAnnotation] outputs.
