-Add 2 attributes to syringefilled : throughput (boolean to kwow if we
work with vol/duration or vol/trhoughput) and update_remaining_volume (a boolean to know when we have to update the remaining volume
-Fix conversions methods of syringe_filled
-fix start_exchange method of syringe_filled
-add graphical interface for the two new attributes
-add a ne button to load syringe database

Fixing arduinoson problems by using singletons for syringe and syringefilled instead of static members.

Adding fuction of the cli interface : FS-SAVE and FS-LOAD to manage the syringyge_filled_json ducument

Every compilation problem have been resolved but the syringe pump does not work with the we interface

Changing id_syringe to name_syringe and also change type from Syringe* to String and do all the changes going with it

 Deletion of setupJsonSyringe(filled) methods because they are repetitive of setter methods and would be called in the constructor, we don't need another method to do it.

manage_emergency to take it into account.

Creation of methods move (which manage movement of the motor) and volume_to_distance which convert a volume to a distance from the syringe model.
