Zuse Z1 inspired mechanical binary counter

Extendable to any bitlength (in theory, see README).
The Z1 certainly had *some* form of binary counter to control its microprocesses (as described in [Konrad Zuse's Early Computers (Rojas, 2023)](https://link.springer.com/book/10.1007/978-3-031-39876-6)), but I couldn't find any images or detailed descriptions of it so I designed one myself using the technology present in the rest of the machine.

Included are assembly pictures.

- The lockB and lockT parts how have hooks to keep them from coming apart without glue
- The control portion now has a stationary handle so you can hold it better while cycling
- There are now retaining rings to clip on to keep everything from falling apart when you pick it up
- Out and OutOrth have received little extra panels that you can put 0 and 1 indicators on
