Optimize memory usage for mobile

This seems to config badger for low memory environments.

janelia-flyem/dvid/blob/master/storage/badger/lowmem.go#L40


	}

	vlogSize, found, err := config.GetInt("ValueLogFileSize")
	if err != nil {
		return nil, err
	}
	if found {
		opts = opts.WithValueLogFileSize(int64(vlogSize))
	}

	// Low-memory options
	dvid.Infof("Using Badger with low memory options.\n")
	opts = opts.WithValueLogLoadingMode(options.FileIO)
	opts = opts.WithTableLoadingMode(options.FileIO)
	opts = opts.WithValueLogFileSize(16 << 20) // 16 MB value log file
	opts = opts.WithMaxCacheSize(8 << 20)
	opts = opts.WithMaxTableSize(8 << 20)
	opts = opts.WithKeepL0InMemory(false)
	return &opts, nil
}

Might help ?
