Enhancement: Restore files with long runs of zeros as sparse files
When using `restore --sparse`, the restorer may now write files containing long
runs of zeros as sparse files (also called files with holes), where the zeros
are not actually written to disk.
How much space is saved by writing sparse files depends on the operating
system, file system and the distribution of zeros in the file.
During backup restic still reads the whole file including sparse regions, but
with optimized processing speed of sparse regions.
