Ignore unterminated string initialization for hexchar

gcc v15+ will add the check for unterminated string initialization as a default, thus causing the build to fail due to the hexchar function. Since this function uses the char array only for mapping an integer to a hexadecimal char, this error can be ignored. Signed-off-by: Michael Engel <[email protected]>
