Input/Output Formats Default to YAML

[maddenp-cu]

Synopsis

Fixes #790 .

Previous behavior example:

$ echo 'n: !int "{{ 1 + 2 }}"' | uw config realize --input-format yaml --output-format yaml
n: 3

New behavior example:

$ echo 'n: !int "{{ 1 + 2 }}"' | uw config realize
n: 3

You can still be explicit as needed, of course:

$ echo "&nl n = 3 /" | uw config realize --input-format nml
nl:
  n: 3

And deducing config format from filename extensions still works as expected, e.g.

$ echo "&nl n = 3 /" | uw config realize --input-format nml -o a.nml
$ cat a.nml
&nl
    n = 3
/

This is a really nice change, especially when it's typically what I want. Thanks!
