Use as in
```
for ii in cpp other tex; do addheader.py --cfg=.pylicense-${ii}.cfg .; done
```

all ranks previosuly created an ofstream object for it w/o anybody but
rank 0 ever touching it

```
Configuration(std::vector<std::string> keys, std::vector<long int> values)
```

[common.configuration] drop obsolete ctor
