added guid field insertion method for geopackage file

[ywkim312]

Test with the attached data.zip file. Unzip the file then there will be epn.shp, guid_no.gpkg, and landcover. gpkg Use the following snippet

from pyincore.utils.geoutil import GeoUtil

# test adding guid to shapefile
def add_guid_shapefile():
    infile = "C:\\rest\\test\\epn.shp"
    outfile = "C:\\rest\\test\\epn_guid.shp"
    GeoUtil.add_guid(infile, outfile)

# test adding guid to geopackage
def add_guid_geopackage():
    infile = "C:\\rest\\test\\guid_no.gpkg"
    outfile = "C:\\rest\\test\\guid_yes.gpkg"
    GeoUtil.add_guid(infile, outfile)

# test adding guid to geopackage
def add_guid_landcover_geopackage():
    infile = "C:\\rest\\test\\landcover.gpkg"
    outfile = "C:\\rest\\test\\landcover_yes.gpkg"
    GeoUtil.add_guid(infile, outfile)

if __name__ == "__main__":
    add_guid_shapefile()
    add_guid_geopackage()
    add_guid_landcover_geopackage()

add guid shapefile and add guid geopackage should work and generate output files but add guid landcover will make an error saying the the file contains the raster and it is not supported. Also please check the output files if they have guid field in it using QGIS or others. Please modify file path to you own. data.zip
