sdc.redistribute 0.1.0

• Initial CRAN release.
• redistribute_direct() performs area-weighted areal interpolation between two polygon layers: extensive (count) measures are total-preserving and intensive (rate) measures are area-weighted means.
• redistribute_parcels() performs dasymetric redistribution across a point layer (such as parcel centroids), splitting each source value equally or in proportion to a weights column.
• Ships the sdc_example dataset and the introduction and method-comparison vignettes.
