Massive improvement of render performance by:
- replacing the codimd-line-marker with an in-memory map
- an observation of the changed markdown code to identify changed lines
- a unique react-key calculation
- added csv-replacer
- changed highlghted-code plugin:
each replacer extracts what he need from the data-extra attribute now
- changed CHANGELOG.md
