Make all top-level disassembly functions accept base, case, and radix
options just like for DISASSEM:DISASSEMBLE. * DISASSEMBLE-SEGMENTS actually implements the base, case and radix options. * DISASSEMBLE doesn't implement the options but calls DISASSEMBLE-SEGMENTS with the appropriate args. * DISASSEMBLE-FUNCTION, DISASSEMBLE-MEMORY, and DISASSEMBLE-CODE-COMPONENT accepts the new keyword args. * Update the docstrings to indicate the new keyword args.
