Partial reads

[reynir]

For some use cases it is desirable to read the data in chunks. A challenge is what to do about the data checksum. The checksum can only verify the data if the whole file is read. One could implement a streaming interface where a handle is used to read the data in chunks while computing a running checksum, and the status of the checksum is returned at the end. Another option is to just offer random access and do nothing about the checksum.

Partial or chunked writes could also be interesting (with their own challenges).
