 * The ft_memchr function finds the first occurrence of the
  character in the string 'str'.

 * It takes two arguments: a 'str' pointer to the string to be
  string to be processed and an int 'letter'
  which is the character to be searched for.

 * It returns a pointer to the first corresponding character
  in 'str', or NULL if the character is not found.
