Multi-digit number input

[8Dion8]

Currently, it is very space-consuming to input a multi-digit number onto the stack. A possible solution is to change the @ operator in the following way:

1. Every sequence of numbers in the input will be put onto the stack as a single multi-digit number
2. Every sequence of other characters will be put onto the stack as a single 0

Currently pushed an update that changes the behaviour the following way:
Every sequence of numbers in the input will be put onto the stack as a single multi-digit number. All other characters are ignored
