Stack:
+ add alks and rlks options in config.topo()
topo: if number of looks is larger than 1, generate multilooked geometry files
+ generate `geom_master` folder in the root directory, same level as `Igrams`
+ import mroipac.looks.Looks module to multilook the full resolution geometry files from `./merged/geom_master`
+ copy over the full resolution xml/vrt files from `./merged/geome` to `./geom_master` as `*.full.xml/vrt` files, to support the number of looks extraction for mintpy
+ bug fixed in extractInfo(). This was not a problem before because the default values are 1 and the custom values from argument was not inputed in the config file.
