-updated github pages
-introduced news and citation pages
-AHN1-AHN3 is currently not supported to be used. Please change it to 'AHN' to always use the latest version made available by PDOK. Currently that is AHN4.
-The default extraction method to receive the AHN elevation is changed to 'simple' (nearest) instead of bilinear. Please see this [article](https://gisgeography.com/raster-resampling/) that explains the difference.
-In this release downloading point clouds is not supported.
-It is now possible to retrieve AHN elevation data at exact intersection points of 2 or more AHN sheets.

Other changes
-AHN4 is the latest full AHN version made available by PDOK. This release now supports this AHN version.
-in `ahn_area()` introduced the ability to only download AHN sheets using the `sheets` parameter.
-Introduced the function `ahn_sheets_info()` to retrieve information about the AHN sheets and which URLs are used for download.
-Removed the ability to use older AHN versions (AHN1-AHN3). It is in the planning to reintroduce this in a future release.
-Removed the ability to download point cloud data from the AHN. This will possibly be reintroduced in a future release.
-Adjusted URLs so that AHN datasets hosted by PDOK can be retrieved again.
-The code now looks at source URLs from data frames instead of hard coded references in the code.
-Efficient checks are built in to see if the AHN version called is currently supported.
-Reorganised code and removed deprecated/unsupported functions.
-Removed all dependencies of the deprecated 'rgdal' package. 'Terra' package is now used instead of 'raster'.
-Updated all the dependent package to the the latest versions.
-improved R syntax throughout the whole code.
