Issue with columnsect.get_field_location(radar, site_lat, site_lon) function

[dhwaniit]

I noticed that there is a problem with pyart.util.columnsect.get_field_location(radar, site_lat, site_lon) function as when we change the precision of lat/lon values, the results are completely wrong means this function doesn't work on high precision lat/lon. not even for two significant digits. for example, if lat=29.48 and lon =-96.15 then it won't give correct and complete profile(only few meters of height can be shown) whereas for 29.4 anf -96.1 it shows complete profile
