[JOSS REVIEW] minor edits to the manuscript

Related to: openjournals/joss-reviews#3722

• please extend the "statement of need" a bit, or rephrase it so that within the first sentence it is already obvious that bam-readcount is not so much just about counting reads, but primarily about collecting metrics that are particularly helpful in judging wether a specific variant call is reliable or not (or maybe that's not even the primary use-case, who knows! :) )
• similarly, the conclusion should state a bit more clearly what precisely the role of bam-readcount is in the bespoke pipelines and the use cases that are mentioned there
• lines 37 and 54 should have "its" instead of "it's"

We've expanded the statement of need, and described the role of bam-readcount more thoroughly in the revised manuscript. Thanks for the typo corrections!

Great update to the text! The use-cases of the tool are very clearly described now, great job!

• There's a typo on line 61, and there might be a letter missing in line 50, too ("disks?").

Thanks - fixed and pushed!
