Display percentage of mapped read of samtools flagstat in general stat table

[JeanMainguy]

Description of feature

Hello,

I would like to display the percentage of mapped reads given by samtools flagstat results in the general stat table. This value is already parsed by MultiQC and can be found in multiqc_data/multiqc_samtools_flagstat.txt with the name mapped_passed but so far I was not able to display it in the general stat table. The only two columns that seem displayable are flagstat_total and mapped_passed.

Is there a way to display the percentage of mapped reads ?

Thanks !
