Create server mirrors

[JoaoCarabetta]

Given the current instability of IPEA server, it might be a good ideia to have mirrors.

Other organizations can host geobr that can be used if the main server fails.

I can modify the python package to support this kind of behavior. @rafapereirabr can implement it on R?

The organization Base dos Dados is willing to support a mirror with a 1 month update rate.

@rafapereirabr let me know what you think. If approved, I can start to work on it ASAP.

Problem connecting to data server.

[rafapereirabr]

I have now finished uploading all files from geobr as assest to release v1.7.0 on github. This means that all files are now simultaneously stored in two servers: our own server at Ipea and on github. For example, the amazonia_legal.gpkg can be found either of the links below.

• "https://www.ipea.gov.br/geobr/data_gpkg/amazonia_legal/2012/amazonia_legal.gpkg"
• "https://github.com/ipeaGIT/geobr/releases/download/v1.7.0/amazonia_legal.gpkg"

I have also made changes to the download_gpkg() and download_metadata() functions so that geobr now downloads the data from Ipea. In case the Ipea link is off line for some reason, then the package tries to download the data from Github. For users, the effect of this change is that the package is much more stable and less vulnerable to instabilities in Ipea’s data server connection.

@JoaoCarabetta , let me know if you would like my help to implement these changes to the Python version of geobr.
