Make the align_trim command in output headers consistent with other programs

[BioWilko]

Description of feature

Currently we end up with lines like this:

@PG	PN:align_trim	ID:align_trim	VN:1.0.1	CL:/opt/conda/bin/align_trim --samfile test.sorted.bam --output test.primertrimmed.bam --report test.align_trim_report.tsv --amp-depth-report test.amp_depth_report.tsv --normalise 200 primer.bed

We should modify this to be a little more consistent with how users will expect it, outputting e.g.

@PG	PN:align_trim	ID:align_trim	VN:1.0.1	CL:align_trim --samfile test.sorted.bam --output test.primertrimmed.bam --report test.align_trim_report.tsv --amp-depth-report test.amp_depth_report.tsv --normalise 200 primer.bed
