Two simple issues: choose 2 schemes & header in the regular output

[eneasdecarvalho]

Hi. Two simple issues:

1 - Maybe it would help if user could choose 1 or more schemes in the --scheme option, similar to what is possible to --exclude option.

2 - Header could be included in the 'regular' output, similar to what occurs in --legacy output. The inclusion of the header could be an option for the 'regular' output.

1. that might be possible

2. you can't really have a header in regular output, because the scheme might not be the same for all the input files. if there was only one input file, then yes it could be possible.
