Bump version to 10.10.6

* Fix image encoding concurrency limit

The current FFmpeg image extractor is configured to use a resource pool size that always equals 2 times the number of CPU cores, which is somewhat excessive. Make the default equal to the core count instead of twice, and respect the `ParallelImageEncodingLimit` option.

* Fix code stype

* Check null value for unit tests
