* feature: Extend VideoWriter to accept vector of parameters - Add additional constructor and `open` method for `VideoWriter` those accept a vector of parameters - Move actual implementation of the `VideoWriter::open` to general method which accepts vector of parameters - Propagate parsed parameters map up to actual video backend construction * fix: Change VideoWriter constructor description to suppress doc warning * refactor: Rollback newlines changes * feature: Changed VideoWriter parameters workflow * feature: Log unused parameters in VideoWriter open * doc: Fix VideoWriter `isColor` parameter description * fix: int to bool VC++ conversion warning * doc: Remove information about `isColor` flag usage.
