No Safari/Chrome iOS 12-13-14, but works on 15-16

It seems on some safari versions ( mobile ?) automatic media startup fails and block whole startup process when it's not the whole WASM engine ! ( iOS <15 )

The actual process is :

1. load an empty.ogg sound and try to play it, catching exception to set a lock.
2. repeat until unlock media play success while displaying the prompt in loading screen ( template default.tmpl )
3. continue and give hand to python code (main.py).

for safari it probably should be:

1. detect safari and do nothing if matching.
2. Display a prompt in loading screen, wait for a mouse click (same event for one finger touch )
3. continue and give hand to python code (main.py).

This would not work if navigator user agent is faked, but unlikely to happen on iOS.

ume fixed for Safari 15, tested on iphone/ipad
keeping it open for safari 13/14 as it may just be a wasm compilation flag problem. But don't expecpt much it is very time consumming to debug.

note chrome is also affected since apparently it share something with safari on iOS
