BREAKING CHANGES

• CellExternalCopyManager now copies via
  navigator.clipboard.writeText and pastes via navigator.clipboard.readText
  (secure context required). The bodyElement and clipboardPasteDelay options
  are removed, _decodeTabularData takes the clipboard text instead of a
  textarea, and paste completes asynchronously. New clipboardWriteOverride /
  clipboardReadOverride plugin options replace the transport where the
  Clipboard API is unavailable. The row split in _decodeTabularData now
  treats CRLF as one delimiter (the decoy textarea normalized CRLF away;
  readText does not).
• ContentIntelligent number and string columns used to read
  every row and now read the first 200. Content columns using the default
  count read 200 rows instead of 100.
• SortableJS is no longer used nor required. Consumers who load
  SlickGrid via script tags can remove their SortableJS <script> include; the
  window.Sortable global is no longer read. Column reordering now requires
  slick.interactions.js to be loaded (it already was in every example). The
  SlickDraggableGrouping.getSetupColumnReorder() return shape changed in the
  previous commit as part of the same effort.
• TypeScript rejects misspelt autosize modes, and a value
  held in a plain string variable needs a type assertion such as
  value as ColAutosizeModeValue. No runtime change.
