Compiler error

[brmarkus]

Under Ubuntu LTS 24.04.3 I got the following compiler error:

/BitNet/src/ggml-bitnet-mad.cpp:811:18: error: cannot initialize a variable of type 'int8_t *' (aka 'signed char *') with an rvalue of type 'const int8_t *' (aka 'const signed char *')
  811 |         int8_t * y_col = y + col * by;
      |                  ^       ~~~~~~~~~~~~

Using CLANG in v18.1.3 and CMAKE in v3.28.3 and GCC/G++ in v13.3.0 and Python in v3.12.3.

Needed to add "const":
811 | const int8_t * y_col = y + col * by;
