feat(puffin): add partial reader

[zhongzc]

I hereby agree to the terms of the GreptimeDB CLA

What's changed and what's your intention?

PartialReader is used to read a contiguous segment of bytes from a resource. For the blob format, by providing the offset and size of the blob, one can utilize PartialReader to read the content of the Blob.
This PR introduces PartialReader and implements std::io::Read, std::io::Seek, futures::io::AsyncRead, and futures::io::AsyncSeek for it.

Checklist

• I have written the necessary rustdoc comments.
• I have added the necessary unit tests and integration tests.
