feat: add momentum indicators and expand function coverage

Browse Source 
Add a full Momentum Indicators category (momentum_indicators.go) with
26 new wrapped functions:

  ADX, ADXR, APO, AROON, AROONOSC, BOP, CCI, CMO, DX, IMI,
  MACD, MACDEXT, MACDFIX, MFI, MOM, MINUS_DI, MINUS_DM,
  PLUS_DI, PLUS_DM, PPO, ROC, ROCP, ROCR, ROCR100, RSI,
  STOCH, STOCHF, STOCHRSI, TRIX, ULTOSC, WILLR

- Register all new native symbols in Load() (loader.go)
- Declare corresponding native function variables in functions.go
- Add MAType enum (ta_ma_type.go) for MA-type parameters (SMA, EMA,
  WMA, DEMA, TEMA, TRIMA, KAMA, MAMA, T3)
- Add taResult constants (ta_result.go) mirroring TA-Lib return codes
- Each wrapper includes a doc comment with formula, interpretation, and
  known behavioral edge-case notes
