Interpolate y values at target x positions using linear interpolation.
This is useful for upsampling or resampling data to specific x positions.
Both the input data and target x values must be sorted in ascending order.
Uses a two-pointer approach with O(n + m) complexity.
Parameters
data: DataXY
object that contains property x (an ordered increasing array) and y (an array).
xTarget: DoubleArray
target x positions where y values should be interpolated.
