develop: Murezzda update timestamps diff dpe groups words by speaker (#174)
* Added timestamp update via diff tool * Added missing function * Commited intermediate state * Rewrote timestamp alignment and differ to be integrated in each other instead of doing a 2-step process. * Update Timestamps now works correctly. * Fixed errors from rebase, removed debug code * Moved UpdateTimestamp into its own folder. * added updateTimestampsSSTAlign which updates the timestamps with the sst-align code * Added timestamp update via diff tool * Added missing function * Commited intermediate state * Rewrote timestamp alignment and differ to be integrated in each other instead of doing a 2-step process. * Update Timestamps now works correctly. * Fixed errors from rebase, removed debug code * Moved UpdateTimestamp into its own folder. * added updateTimestampsSSTAlign which updates the timestamps with the sst-align code * Added documentation * Merged timer for updating the timestamps and local save. * Selection state is now kept across updates to timestamps * Fixed bug where words with punctuation always are considered as new words. Timestamp update function now also uses the alignWords function directly instead of alignJSONText, removing some overhead. * Fixed small bug which raised an error if an empty block was present during timestamp update * Changed time of timestamp-update. Now re-calculates the timestamps after 5 seconds if the transcript has been edited or if the user saves the transcript manually with the save button * Code cleanup * some changes to show sudgestions for PR * added some of changes sudgested in PR * adjusted DPE adapter so that it preserves paragraphs break within contiguos speakers * fixed one test * commented out auto align left aligning as a step before save btn and before export function, rather then as a step that happens everytime autosave is triggered, as that might be unecessary, and add performance overhead, I also noticed the cursor position jumped after realignement, thought something was been put in place to preserve/avoid that?
