feat: Add Prime method to various indicators for initializing state with historical data
- Implemented Prime method in Vel, Ao, Apo, Frama, Adl, Adosc, Aobv, Cmf, Efi, Eom, Iii, Kvo, Mfi, Nvi, Obv, Pvd, Pvi, Pvo, Pvr, Pvt, Tvi, Twap, Va, Vf, Vo, Vroc, Vwad, Vwap, and Vwma classes. - The Prime method resets the indicator state and processes the provided historical bar data to initialize the indicator. - Added warmup period property to Adl and Wad classes to define the minimum number of data points required for validity. - Updated benchmark tests to use Batch methods for performance evaluation.
