Revert "Remove minimum of 10 buffers in constructor, some cameras onl…

…y allow 2"

This reverts commit 6e9ff68.

Only being allowed 2 buffers was not due to the camera, but due to too little RAM.
The system only had 4 GB, and Spinnaker only allowed 2 buffers.
But the camera did not actually work correctly with only 2 buffers.
The solution is to add more RAM, and then 10 buffer minimum is OK.
