v0.3.0

Performance upgrades

Various performance upgrades, particularly for working with high resolution grids.

In create_raster_polygons:

• replacing the for-loop assigning pixels to polygons with a lambda apply
• creating flexible buffer for subsetting to bounding box, replacing the hardcoded 0.1 degrees used previously with twice the max grid spacing

In aggregate:

• an optional replacement of the aggregating calculation with a dot-product implementation (impl='dot_product' in pixel_overlaps() and aggregate()), which may improve performance in certain situations

Expanded functionality

Weightmaps can now be saved using wm.to_file() and loaded using xagg.core.read_wm(), and no longer have to be regenerated with each code run.
