feat: add Input and Output trace generation to the prove_brainfuck entrypoint

[zmalatrax]

To commit the trace when generating the proof with the prove_brainfuck() entrypoint, we must evaluate the BaseField that populates the IOTable on the Circle domain.

To do so, we must pack the registers of each row IOTableRow into a BaseColumn, which provides us a Vec<BaseColumn>
There is only one register, mv, so it is pretty straightforward (convert all the Vecinto a singleBaseColumn`

Then we evaluate each row (i.e. BaseColumn) on a corresponding circle domain.
