check: tagschecking: tests for tags serialization in muxers
Adds a check unit test that aims to test tags serialization and deserialization consistency (in muxers). It provides a basic function that allows one to easily specify tags, a muxer and a demuxer and a test will be done to check if the tags have been consistently muxed and demuxed
