[Language idea] Add support for calculations in turtle commands

[boryanagoncharenko]

Language idea incl level Now that the turtle commands are available for all levels, we should allow them to take more complex parameters such as expressions.

Additional context The following program should work:

for counter in range 10 to 100
    turn 100 - counter
    forward counter

I like this idea! Shouldn't be too hard, can I take this one, Boryana, or will you work on it?

Apologies for the delay. I have not started working on this, so please feel free to pick it up.
