void Lz4DecompressReader (uint64_t offset, uint64_t decompressed_length, std::shared_ptr<Reader> compressed_reader)Lz4DecompressReader will decompress data starting at |offset|. That is the compressed data is
embedded in |compressed_reader| and the first compressed byte is at |offset|.

fpromise::result<void, std::string> Read (uint64_t offset, std::span<uint8_t> buffer)On success data at [|offset|, |offset| + |buffer.size()|] are read into
|buffer|.
On error the returned result to contains a string describing the error.
