feat(overlap): add advanced overlap studies wrappers and wire TA-Lib symbols

- add TA-Lib function pointer signatures in functions.go for: MA, MAMA, MAVP, MIDPOINT, MIDPRICE, SAR, SAREXT, SMA, T3, TEMA, TRIMA, WMA - register new symbols in Load() via purego.RegisterLibFunc in loader.go - add public overlap study wrappers in overlap_studies.go with consistent nil-on-failure behavior - update README overlap studies list to match implemented API
