    std::string point_file,
    std::string polygon_file,
    double zone [4],
    std::vector <std::vector <int>>& results
    )

strtree_contains geosptial contains (point in polygon) based on strtree

Parameters:

mode	0: no fpga, 1: index function is accelerated by fpga
x_col	the column number of x in point csv file
y_col	the column number of y in point csv file
point_file	input point csv file
polygon_file	input polygon file
results	The id of the first dimension represents the polygon id, and the content represents the point id
zone	[xmin, xmax, ymin, ymax], Limit the scope of point and polygon.

Returns:

total size of results
