 * \brief Write a C representation of arr to os.
 *
 * This function generates a comma-separated, indented list of C integer listeals suitable for use
 * in an initializer. The Tensor is flattened and then the list is produced element by element.
 * For the int16_t Tensor [-3, -2, -1, 0, 1, 2, 3, ...], and indent_chars = 4, the following output
 * is produced:
 *     -0x0003, -0x0002, -0x0001, +0x0000, +0x0001, +0x0002, +0x0003
 *
 * \param arr The array to generate
 * \param indent_chars Number of chars to indent
 * \param os Output stream where the array data should be written.
