Reads @stream and writes the data from it to @handle.
Before calling this function, you may need to call [method@Rsvg.Handle.set_base_uri]
or [method@Rsvg.Handle.set_base_gfile] to set the "base file" for resolving
references to external resources. SVG elements like
<image> which reference external resources will be
resolved relative to the location you specify with those functions.
If @cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the
operation was cancelled, the error G_IO_ERROR_CANCELLED will be
returned.
