Use the simple Cranlogs API to obtain half-yearly R package downloads summaries in 2018

The R-Hub cranlogs API is a very simple API to query using a web browser or R. You can read more about this API here: https://github.com/r-hub/cranlogs.app

This task involves using this API to obtain data for total R package downloads for a specified period of time.

Example 1 - Using a web browser: Copy and paste the following URL into a web browser https://cranlogs.r-pkg.org/downloads/total/2019-01-01:2019-06-01

The response is a JSON object that contains the start date (Jan 01, 2019), end date (Jun 01, 2019) and the total download of all R packages for the time period.

Example 2 - Using R: install the jsonlite R package. Then from the R console execute this statement: jsonlite::fromJSON("https://cranlogs.r-pkg.org/downloads/total/2019-01-01:2019-06-01")

Now, the task is to obtain the total downloads of all R packages in 2018, half-yearly and save the results in a single CSV file. This means you will obtain total downloads from January 01 to June 30, and from July 01 to December 31 for the year.
