Create bit.ly links to common datasets

[maurolepore]

This will be helpful to train partners in how to deal with raw data.

Useful links:

• to data-raw/database-output/, so the entire collection of files can be downloaded with usethis::use_course(). This includes a .Rproj file and a data-raw/ directory, to show learners how to organize a project.

For example:

A zip file that lives here:

https://github.com/forestgeo/fgeo.opendata/blob/dev/inst/database-output.zip

Can be downloaded with (note that blob is replaced by raw):

use_course("https://github.com/forestgeo/fgeo.opendata/raw/dev/inst/database-output.zip")

• to each individual file in data-raw/, for cases when a single file is what matters for a particular demonstration.
