neurolab throws an exception with numpy version 2

[Nadine45832]

Hi,

I was working on my lab in college and I ran into a problem. I installed numpy latest version (2.1.3) and neurolab latest version (0.3.5) in my environment. When I import both of them, numpy inside neurolab throws an exception:

`np.Inf` was removed in the NumPy 2.0 release. Use `np.inf` instead.

This is a call stack:

Traceback (most recent call last):
  File "NeuralNetworks/nn.py", line 2, in <module>
    import neurolab as nl
  File "NeuralNetworks/venv/lib/python3.12/site-packages/neurolab/__init__.py", line 54, in <module>
    from . import net
  File "NeuralNetworks/venv/lib/python3.12/site-packages/neurolab/net.py", line 38, in <module>
    from . import trans
  File "NeuralNetworks/venv/lib/python3.12/site-packages/neurolab/trans.py", line 51, in <module>
    class PureLin:
  File "NeuralNetworks/venv/lib/python3.12/site-packages/neurolab/trans.py", line 70, in PureLin
    out_minmax = [-np.Inf, np.Inf]

Looks like the fix is simple: update numpy andnp.Inf should be replaced with np.inf.
