Description of feature

Hello, first of all thank you for your effort in maintaining and improving the pipeline.

I noticed that .tab files produced by deeptools take up a lot of space even though they can be compressed to ~15% of the original size.

This is the size of all files in the results folder grouped by extension :

[...]
49.7M	.broadPeak
52.2M	.xls
65.5M	.bed
68.7M	.gappedPeak
238.9M	.txt
1.1G 	.bigWig
1.4G 	.gz
2.9G	.fa
9.2G	.bam
13.3G	.tab
27.9G	<NoExtension>
56.5G	Total

After compressing the .tab files with the default options of gzip:

[...]
49.7M	.broadPeak
52.2M	.xls
65.5M	.bed
68.7M	.gappedPeak
238.9M	.txt
1.1G 	.bigWig
2.9G	.gz
2.9G	.fa
9.2G	.bam
27.9G	<NoExtension>
44.7G	Total

The majority of tab files come from results/star/merged_library/deeptools/plotprofile/.
Furthermore, when building a star index the genome used is copied uncompressed in results/genome/, which can be compressed to easily recover ~2GB of space.

Thank you!
