[QOL] add support for binary and octal notation for number parsing

[GTG3000]

The number input window supports 0x... hexadecimal notation, so it stands to reason it'd be nice to have 0o... and 0b... for octal and binary respectively. I *think* I recall that the string parsing is using an in-house solution from some friday facts, so shouldn't be difficult to add?

Is there any reason to actually use this though? Sure, it might make sense from a completeness sake, but I bet few even use the hexadecimal option, save for maybe the few people building entire CPUs/ASICs/FPGAs/whatever with circuit networks.
