Merge branch 'develop-standalone' into develop. Close #170.

**Description**

The CLI of Ogma lacks uniformity: some commands are driven by the input
format, others by the output format (e.g., ROS, cFS). To make Ogma
easier to use, we should provide an interface that is driven by one or
the other, but not both.

**Type**

- Feature: Introduce new command.

**Additional context**

None.

**Requester**

- Ivan Perez.

**Method to check presence of bug**

Not applicable (not a bug).

**Expected result**

Ogma provides commands for inputs support, or for outputs/targets
supported, but not both.

**Solution implemented**

Make JSONFormat descriptions readable so that they can be read from text
files.

Introduce new command `standalone`, both at core and CLI, that
implements the ability to read a spec and convert it to Copilot.

Remove dedicated/redundant commands.

Adjust tests as needed to use the new interface.

Adjust documentation.

**Further notes**

None.
