mzTab to verbose with repeated data.

[ypriverol]

Description of feature

@daichengxin @jpfeuffer :

I have found that the mzTab files (specially for big projects) are really huge, an mzTab with thousands of mzMLs can end up with a lot of columns with null values. In terms of storage, this is can have a huge impact, for example: PXD016999: mzTab (uncompress) 160GB -> mzTab (gzip) 2GB.

We should implement a last step (it can be optional --compress which compress big files) in the pipeline to gzip some of the files:

• mzTab
• mzML

What do you think @jpfeuffer @timosachsenberg @daichengxin
