mkvmerge: Matroska reader: when reading WebM files that use block additions with ID 4 (HDR for VP9) an appropriate block addition mapping will be created automatically.mkvmerge: the maximum block addition ID track header value is now calculated automatically from both the existing mappings & the actually used block additions in the block groups.

Currently only implemented for Matroska files where it contains the number of cue points. mkvmerge: JSON file identification: added a child element called `num_index_entries` to the `properties` track element containing the number of index entries found for a track.Removing block additional data is not possible anymore, as it is often required for proper decoding. mkvmerge: removed the option `-blockadd`.
