Create BEES MAGINC operator

Create an operator which, when banged with a number n, interogates the input value of whatever it's output is connected to, then outputs n + the number.

This can be used, for example, in conjunction with white whale's param input & CV sequencing - white whale can update it's param input when you hold down a bottom row button. Then you connect the DELTA output from an ENC to the PARAM input (via MAGINC).

So effectively, MAGICINC adds an ACCUM to any input, but with the added bonus that the accumulated input value may be dynamically updated by it's parent op via a grid (or timer) interaction...

• create & test maginc operator
• modify whitewhale CV to use the functionality
• enc operator DELTA output should scale output by STEP input
