fix: allow for no gmaps_key input, add new parameters, fix .onLoad check

[laresbernardo]

• feat: Allow for users to use commuting_zones() without the need of fetching the coordinates using Google's API.
• feat: Enable new parameters: quiet, longitude_col_name, latitude_col_name, …
• fix: .onLoad warning when checking the code with devtools::check()

thanks a thousand:) while you're doing it already, can you also adapt the readme and the website (under website/doc/Walkthrough/Walkthrough.md), then I can deploy the website change too.

LGTM!

Currently testing the integration in GL, because it throws error when running:

GeoTestData_PreTest <- GeoDataRead(data = GeoLift_PreTest,
                                   date_id = "date",
                                   location_id = "location",
                                   Y_id = "Y",
                                   X = c(), #empty list as we have no covariates
                                   format = "yyyy-mm-dd",
                                   cluster_locations =T,
                                   find_location_lat_long = T,
                                   summary = TRUE,
                                   country_name = "United States"
                                   )

@NicolasMatrices-v2 please check. Thanks for your comments and feedback. I tend to avoid stop() errors when not 100% necessary; this might be an example where that's the case.

@NicolasMatrices-v2 @gufengzhou any updates here? Are we ready to merge after the changes suggested?
