[FEATURE] Optimize read_redcap for Batch processing

[rsh52]

Feature Request Description

The following is resultant of meeting with Will on 2022-12-08

For extremely large databases, the preferred method of data extraction from REDCap switches between oneshot and "batch" methods (i.e. those supplied by REDCapR::redcap_read).

For smaller databases, reading in REDCaps using batches can be slower, so it is not always a great solution. We should determine a way to assess REDCap database size at onset and then send the extraction call to the appropriate function.

To note, the real draw to this is an increase in reliability that batch reading can provide over oneshot methods, even though oneshot is simpler and faster for most databases.
