add stream writer this should improve streaming write performance, which is common in many cases, e.g., copying large files. This is additional to improved random read write operations: https://github.com/chrislusf/seaweedfs/wiki/FUSE-Mount/_compare/3e69d193805c79802f4f8f6cc63269b7a9a911f3...19084d87918f297cac15e2471c19306176e0771f 2021-12-25 06:38:22 +00:00			`package page_writer`
