enable Deterministic Chunk Requests
Enables deterministic chunk sizes and offsets when streaming the PDF file using an IRandomAccessDataSource instance.
Deterministic chunk requests are useful for caching chunks locally as the same offsets will be used in future requests to RandomAccessDataSource.fetchChunk(). Setting enableDeterministicChunkRequests
to true will consume up to 16 MB more of memory in order to prevent multiple requests of the same chunk.
