Improve binary support

[vinc]

• Add support for 0b1000 format in Lisp
• Remove support for 0XC0DE format and keep only 0xC0DE (and 0xc0de) in Lisp
• Use 0xC0DE format everywhere instead of 0xc0de
• Rewrite hex command to handle even number of bytes in binary
• Show correct memory address in elf command
