Add tin.py output to MultiQC report
When adding the rseqc/tin the TIN files are being found by MultiQC (v1.11) but I can't seem to be able to get rid of the markdup.sorted.bam extension as shown in the image below:

This doesn't work either: https://github.com/nf-core/rnaseq/pull/745/commits/169d5470b7de4da2757471dccd773a9f9dc98465
So for now I am using the wrong search path intentionally as added in https://github.com/nf-core/rnaseq/pull/745/commits/dabdfee63ed5dceb638c96180b96b3f37c59e7d6. This means the files will all be staged in the MultiQC work directory but they won't be rendered in the report.
This behaviour needs to be tested with the dev version of MultiQC and added back in properly in the next release of the pipeline.
For now, users should be able to use their own --multiqc_config to add the TIN metrics if they so wish.
This will be fixed in MultiQC v1.12 https://github.com/ewels/MultiQC/issues/1484
MultiQC v1.12 was released recently but I found an issue with the rendering of the custom content of dupRadar that needs to be addressed before we bump versions and fix this issue too https://github.com/ewels/MultiQC/issues/1629
Fixed in https://github.com/nf-core/rnaseq/pull/874/commits/77d49ddeea097599601fb5253aface07d63839f7
