Enhance CDO
The CDO post-processing received some functional updates:
- If multiple files are processed, one can use PASSEACH as OUTPUT to pass the result of each individual file to the next operator, which receives multiple input files or acts in parallel on multiple files.
- Filename substitution is now possible also when selecting some variables form the input as well as when chaining with the PASSEACH option.
Closes #139 .
