Assignment in numpy interface doesn't compile

[and-ivanov]

Describe the bug

error: cannot convert ‘dace::ArrayViewIn<float, 0, 1, 1>’ to ‘float*’ in assignment
         __tmp0 = dace::ArrayViewIn<float, 0, 1, 1> (a + 0);

To Reproduce

import numpy as np
import dace

@dace.program
def foo123(a : dace.float32[2], b : dace.float32[2]):
    b[0] = a[0]
    
A = np.array([1,2], dtype=np.float32)
B = np.array([3,4], dtype=np.float32)

foo123(A, B)

print(A)
print(B)
