Performance issue when loading transcript in paper edit

[pietrop]

There's a performance issue when loading transcript in paper edit.

The current way of adding highlights is very process intense and triggers the debugger coz it's running out of memory when used in Adobe CEP Panel.

Raising it here as opposed to the DPE Adobe CEP Panel repo, coz it has to be addressed in the React component that does the highlights interpolation in the transcription's text

one workaround while finding a solution, might be to disable the highlights feature as a way to do a working release. and then re-introduce it once performance has been fixed.

Adding a delay so that it adds the transcripts with the highlights after the components is mounted see this commit for details fbb5b61

Tested in adobe CEP, still a bit sluggish but at least the page loads...

while I can figure out a better way to avoid for the transcript / annotation interpolation to take up soo much memory, I added a btn to delay the process, and do them one at a time as a workaround when working with Adobe CEP

Should test this after having added code splitting
