Fxing problem in initialisation (it was moving and not initialising  and changing visibility true/false to enability (for the button initialisation) so it cannot be used when we don't want it to) (Imust now change the colors in that case by creating a ne style)

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

Correection of the way to use arduinoJson structure, and cretio of a name attribute to use it as the key

Split motor.h into motor.h an motor.cpp, dding a few fuction (some setters missing and conversion) and adding comments.

changing forward_clockwise to _clockwise_equals_forward in motor.h (to fit the way to use it in syringefilled.h)

Changing the name of _retain_accel to _acceleration_mm_per_sec_per_sec in motor class (so it fit better and lt us know t unit)

 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.
