feat: add math operator wrappers and align TA-Lib binding types

Browse Source 
Add Go wrappers for additional TA-Lib math operators:
Div, Max, MaxIndex, Min, MinIndex, MinMax, MinMaxIndex, Mult, Sub, and Sum.

Refactor the TA-Lib function signatures to use int32 consistently,
including taResult and Hilbert Transform bindings, so the Go layer
matches the native library more closely.

Fix HT_TRENDMODE to return []int32 and update related comments and
naming for better API consistency.
