Migrate library/device/test/README to experimental namespace

[Nicogene]

As suggested by @drdanz in #114 all the component has been migrated under the experimental namespace.

This is a first step towards #114

[Nicogene]

telemetryDeviceDumper tested (see #115 (comment)).

In the dumped data I noticed some strange things.

The encoders are fine:

The velocities has strange spikes, but I suspect that are gazebo-related, they not seem corrupted data as in the past

The accelerations are 0, but reading from the /icubSim/left_arm/stateExt:o I get 0 too:

maybe the acceleration are not computed in gazebo @traversaro ?

(Sorry for the missing unit measures, Encoders -> x:seconds y:deg, Velocities -> x:seconds y:deg/s)

[Nicogene]

Except for those spikes, the velocities looks fine:

[traversaro]

Shall I open an issue for that?
