add packages to section 'specific geospatial data sources of interest'

[Rafael H M Pereira]

Hi Roger, I would like to suggest adding the following packages to the section specific geospatial data sources of interest:

• chilemapas provices access to spatial data of political and administrative divisions of Chile
• geobr provides easy access to official spatial data sets of Brazil for multiple geographies and years
• geouy loads and process geographic information for Uruguay
• RCzechia downloads spatial shape files of administrative regions and other spatial objects of the Czech Republic

CRAN links:

• chilemapas
• geobr
• geouy
• RCzechia

Thanks, Roger !
