diag(premiere-plugin): v1.2.3 — file-log around importFiles call

Writes timestamped pre/post lines to C:/Temp/df-import-log.txt around the importFiles call so we can see whether importFiles hangs (only pre line present) or returns and evalScript callback gets lost (both lines present). Diagnostic only.
