aopdata v1.0.0 (dev version)

Major changes

New function aopdata_dictionary() to aopdata data dictionary on a web browser.
All data sets are now simultaneously stored on github and on Ipea’s server. The package now downloads the data from github. In case the github link is off line for some reason, then the package tries to download the data from Ipea’s server. 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.
New data sets:
- Year coverage
  - Access and Land use data sets now cover years 2017, 2018 and 2019
- New cities
  - Data for Goiania now covers the entire metro area of Goiania in 2019.
- New modes
  - Access data now bring accessibility estimates by car
- New activities
  - Land use and access data now bring data for centers for social assistance (CRAS)
  - Population data sets with minor spatial corrections to smooth spatial distributions
