Refactoring of the yarpdataplayer module

[vtikha]

This PR involves a complete refactoring of the yarpdataplayer module. With @vvasco, we implemented the yarpdataplayer library in order to separate the GUI from the processing and thus create a console version of the yarpdataplayer.

This has been done following the structure of the other GUI / console modules eg: yarplogger and yarpmanager

This PR addresses the following opened issues in YARP concerning the yarpdataplayer:

• #2400: yarpdataplayer --hidden cannot start on headless system
• #2401: yarpdataplayer closes immediately after loading data with --hidden flag is used
• #2151: step command in rpc exhibits odd behaviors
• #2140: Provide status flag to check if player has finished playing a loaded dataset
• #1144: yarpdataplayer enhancements

The new version of the yarpdataplayer has been tested on:

• macOS: Catalina (10.15+) and Big Sur (11.1 +) (not with Xcode)
• linux: 18.04 and 20.04
• windows: Windows 10

Here are some screenshots:

GUI version

Console version

Aside all the commands available on the yarpdataplayer, the user can still make use of the following commands in rpc:

The yarpdataplayer-console on the other hand allows the user to:

As a further note, not included in the changes that we did for this PR, we wanted to add some progress bars in the console version of the dataplayer to make things clearer, and found this very powerful library.
Before going ahead with this, and including the files as is, @vvasco and me wanted to discuss about a "nicer" way to include this lib into YARP so that other terminal modules such as the yarprobotinterface and other, can make use of it. The licence is MIT so it should be ok, but let's discuss this further if this is deemed interesting for YARP.

LGTM, thanks.

(Reminder to myself: the scripts/admin/update-license and COPYING file should be updated, since the yarpdataplayer-console tool is LGPL)

About the indicators library, I'm in favour of including it in YARP, the MIT license is compatible with the BSD-3-Clause, therefore I think it is safe to include the single header version in extern with a corresponding README.txt file (see extern/catch for an example).
Probably you should import also the LICENSE and LICENSE.termcolor files.
You might also have a look at the COPYING file, and see if the MIT license should be mentioned there, but I think it is not required.

I'm not sure what's wrong with the CI, the failing builds do not produce any output... let's try rebasing this again

It was some problem on github action, after the rebase everything was built successfully.
Merged, thanks!
