Use binary literals and consts for CPU constants

[SubstituteR]

For things that are constant in the CPU, such as CC max (binary 11) we can use constant literals to make code easier to digest for new contributors.

Example:

// definition
public const byte CC_Max = 0b11 << 6;
// OR
public const byte CC_Max = 0b11000000;
//
// later in the code
//
case 0x30: //   JEQ 
    if ((SW & CC_Max) == 0)
    {
        PC = TA;
    }
    else { this.PC += 3; }
    break;

Alternatively, we can consider making them static and initializing them using their actual values, e.g.

public static byte CC_Max = 0b11;

and later either translate them as needed or simply doing the conversion during the declaration, not sure, we can get creative.
