-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

Delete some reset_position we don't need anymore due to mo_to_mm and move_to_mm_limi_switch distinction (in motor class)

Using lamda functions to match our new ESPUI modifications (which includes deletion of void* parameters in callbacks methods)

Create a Web class with everything static (that is not a problem because we only need one instance of this class

Creation of a function nammed number_max_min to set min an max of control type number (so the volume can't be negative for example)

Changing method move from syringe_filled to start_exchange to make it easier to use (and more adapted to our need now.

Adding a few methods in motor.cpp to have the distinction between move and moveTo from the Accelstepper librairie. In fact I created same methods using moveTo but using move and I change comments t explin how it works.

I think it would be useful to see later if we are using all these methods
or if some of them can be deleted.

Add a limit switch status indication and using syringe_pump_off istaed of syringige_filled.move so the visual change a the same time

The problem was that i diddn't get the usefulness af the former attribute
retain_accel, which is useful for the use of the limit switch, I change
back the name and rename move_to_mm to move_to_mm_limit_switch and
move_mm to move_to_mm
