Add Bing support

[dieghernan]

Following #62 , I have implemented Bing:

Docs:

• Single Geocode/Reverse Geocode: https://docs.microsoft.com/en-us/bingmaps/rest-services/locations/
• Batch Geocode: https://docs.microsoft.com/es-es/bingmaps/spatial-data-services/geocode-dataflow-api/

About Bing batch geocoding service

It is very similar to Batch Geocoding on HERE (see #74), in the sense that it is a POST/wait/GET process with a maximum limit of 50 addresses and really slow, so the user must force batch geocoding with geo(method="bing", mode="batch")-

I pulled in your PR on the bing branch. Batch geocoding is working for me, but I'm getting NA results with single geocoding:

library(tidygeocoder)
geo(sample_addresses$addr[1:3], method = 'bing', full_results = TRUE, verbose = TRUE)

The only code change I made was to allow the user to pass custom_query to the batch geocoder function.

Looks like the issue was just that extract_results() wasn't getting the format it expected for latitude and longitude. The commit above fixes this.

Thanks! The extract_results() for Bing was a bit challenging, I have to say. I guess it broke after I merged main with the latest changes, good catch @jessecambon
