Cap stepsize differently for RISP

[RemDelaporteMathurin]

This pull request includes several modifications to the src/hisp/festim_models/mb_model.py, src/hisp/model.py, and test/test_mb_model_festim.py files. These changes primarily focus on updating model settings, refining mesh vertices, and enhancing the handling of specific pulse types in the model. Additionally, the test cases have been updated to reflect these changes. The most important changes are summarized below:

Model Settings and Mesh Refinement:

• src/hisp/festim_models/mb_model.py: Updated the max_iterations to 30 and adjusted the atol and rtol values for various model creation functions (make_W_mb_model, make_B_mb_model, make_DFW_mb_model). [1] [2] [3] [4]

Pulse Handling Enhancements:

• src/hisp/model.py: Added special handling for "RISP" pulses in the max_stepsize method, including setting specific step sizes and milestones for real RISP pulses. [1] [2]

Test Case Updates:

• test/test_mb_model_festim.py: Updated the test cases for different models (test_mb_W_model, test_mb_model_B, test_mb_model_DFW) to use a higher temperature value and set the initial step size value. [1] [2] [3] [4] [5] [6]

note to self: should we add another test later with high fluxes?
