Feature:Add Built-In BCD Adder Component to CircuitVerse

[blazethunderstorm]

Is your feature request related to a problem? Please describe

Currently, CircuitVerse does not have a built-in BCD Adder component. Users have to manually create one using logic gates and subcircuits. This makes it harder for students to learn decimal arithmetic in digital systems.

Describe the solution you'd like

I’d like to contribute a BCD Adder component to CircuitVerse. It will:

1)Add two 4-bit BCD numbers

2)Output a corrected 4-bit BCD result and carry

3)Add 0110 (6) correction if the binary sum exceeds 9

This component will make it easier to build and teach decimal-based digital systems like calculators.
