Refactor indicators to support optional time step in Prime method

- Updated the Prime method signature in multiple indicators (Jma, Kama, Lsma, Mama, Mgdi, Pwma, Rma, Sma, Ssf, Super, T3, Tema, Trima, Usf, Vidya, Wma, Atr) to accept an optional TimeSpan parameter for improved flexibility.
- Added unit tests for Lsma to verify Dispose functionality, ensuring proper unsubscription from the source and thread safety.
- Enhanced Mama and Wma classes to handle non-finite inputs gracefully and added checks for valid parameters in constructors.
- Introduced additional tests for T3 to validate constructor behavior with invalid volume factors.
- Ensured all indicators maintain consistent behavior when handling edge cases, such as empty buffers and non-finite values.
