Add TSAM script and deps

[henhuy]

TODOS:

• make linter happy
• fix too many sequences and strange file prefixes

[srhbrnds]

The script time_series_aggregation.py is not yet generic enough to automatically aggregate all possible sequence data with tsam and return a new oemof-tabular datapackage. This is due to the partly different naming of the sequence csv-files and the column names of the sequence data. I will try to fix this. @henhuy could you send me the oemof-tabular data package with which you tested this?

I ran into some problems with pre-commit hooks, but i'm still on it to fix this.
