This capability provider implements the wasmcloud:blobstore capability for
Unix and Windows file system. The provider will store files in the local host where the
provider executes.
Build with 'make'. Test with 'make test'. Testing requires docker.
The provider is configured with the link configuration value ROOT=<path> which specifies where files will be stored/read.
The default root path is /tmp. The provider must have read and write access to the root location.
Each actor will store its files under the directory $ROOT/<actor_id>.
