[Dynamic Data] Saving your datas in a file and loading other from a file

[PierreFonda3D]

Saving data to files and loading data from files

This PR adds new functionalities related to data saving and loading.
You can now save and load data from a simple click in the UI.

Scripts

Core/Scripts/UI/DataManager/SDataSaveLoad.cs

Script that listens to UI buttons and handles saving/loading data to files located in:
\SofaUnity\Core\Scripts\UI\DataManager\DynamicDataSaves

Data is saved as JSON and read back by the same script.

Example of a saved file format:

{
    "dataName": "amplitude",
    "optionalCustomName": "Amplitude Oscillator",
    "value": "1",
    "dataType": 2
}

Core/Scripts/UI/DataManager/DynamicSDataManager.cs and DynamicSdata.cs

Code cleanup and addition of an optional custom name functionality.
By default, the data name is used if no custom name is provided.

Missing:

• Vec3 compatibility Save
• Vec3 compatibility Load
• Test in build mode to see if path are working

a few changes in the code.
Also could you add an example in the folder: SofaUnity/Scenes/Examples/
something like: Example_11_LiverDataUI (or another SOFA scene) with a json files containing values.

You could also put it in: SofaUnity/Scenes/Demos/UI/ if you think several examples could be useul to illustrate the Data loading/saving

example scene i wanted to add a Vec3 but there is none that don't break everythings

[PierreFonda3D]

• Still need to find an example Vec3 on the new demo scene if possible

in the caduceus.scn you can add: <ConstantForceField indices="0" totalForce="0 1000 0"/>

<Node name="Snake" >
        <SparseGridRamificationTopology name="grid" n="4 12 3" fileTopology="mesh/snake_body.obj" nbVirtualFinerLevels="3" finestConnectivity="0"/>

        <EulerImplicitSolver name="cg_odesolver" rayleighMass="1" rayleighStiffness="0.03" />
        <CGLinearSolver name="linear solver" iterations="20" tolerance="1e-12" threshold="1e-18" />
		<MechanicalObject name="dofs"  dy="2" position="@grid.position"/>
        <UniformMass totalMass="1.0" />
        <HexahedronFEMForceField name="FEM" youngModulus="30000.0" poissonRatio="0.3" method="large" 
        updateStiffnessMatrix="false" printLog="0" topology="@grid"/>
        
        <ConstantForceField indices="0" totalForce="0 1000 0"/>

		<UncoupledConstraintCorrection defaultCompliance="184" useOdeSolverIntegrationFactors="0"/>
