This sets bit [offset] of [address] to on.
The offsets used are different bits to be toggled on and off, typically there is only one address used in a script.
Example:
MISC::SET_BIT(&bitAddress, 1);
To check if this bit has been enabled:
MISC::IS_BIT_SET(bitAddress, 1); // will return 1 afterwards
Please note, this method may assign a value to [address] when used.
