Add support for slicing joinable data items #14
Description
A common data format with stream2py is chunks of data like segments of waveforms that can be joined together.
The issue is with the BufferReader.range() returns a list of chunks often with extra to trim off at the start and stop since the query falls somewhere inside a chunk. For these cases, it would be good to have range join and trim to get a more exact query.
I would add optional abstract methods to SourceReader that are for joining and slicing read data items and have BufferReader.range() use that and return a single joined data item
