"""Step 8: build the EML mod into the repository (mod/<id>: the result that is committed).

usage: mod      then `python install.py` copies it into the game and dry-runs it
The mod replaces each note's EN sound (the Russian slot does not exist in VoiceoverResource: its fixed
languages are EN/DE/FR/ES/ZH): SoundResource.streamedData points to the new QOA content, frameCount and
duration follow it, VoiceoverResource.durations[EN] too (10 ms units). The game files are not touched:
EML (dbghelp.dll proxy) patches enshrouded.kfc at launch and keeps enshrouded.kfc.bak (emm restore).
