feat: Reset to zero for Leaky

Context

The goal of this MR is to add an option to select a soft reset (subtraction, eq.1 ) or a hard reset (reset to zero, eq. 2) when creating a Leaky Operator.

$$U[t+1] = βU[t] + I_{in}[t+1] - RU_{thr} \tag{1}$$

$$U[t+1] = βU[t] + I_{in}[t+1] - R(βU[t] + I_{in}[t+1]) \tag{2}$$

Note that for the implementation of hard reset, the potential is reset to zero in the next step, so if we have a spike at step

$s=0$

, then we start

$s=1$

by setting the memory to zero, and proceed with computing the potential by taking the input.

Modified files

• MetaOperatorDefs.hpp: Add a LeakyReset enum and change Leaky constructor;
• Leaky.cpp : Use the additional LeakyReset constructor parameter to create the Leaky node;
• pybind_MetaOperator.cpp: reflect the changes made to the constructor;
• Test_MetaOperator.cpp: Test the instanciation of a Leaky node with reset to zero;

Note: More tests have alaredy been written in aidge_backend_cpu to assert that the behaviour is correct.

What is the status of this MR?

I need to understand why the pipeline is failing.

So is it work in progress? I just need you to add the right status label to your merge requests
