Add proof of concept implementation of mzTab-M export

[hechth]

The mzTab-M standard for reporting MS-based metabolomics annotation as proposed by the HUPO-PSI would be the appropriate standard to export the results.

Since this is quite an experimental feature, I think implementing it here could make sense, since it also comes with some deps.

The idea is to import the original mztab-m file, the scores json and the abundance table for the query features and then export a full mzTab-M file.
