Throttling/n-parameter deobfuscation not working

[litetex]

Currently the n-Parameter deobfuscation is not working (we get an empty string for n).

We should check if this is still required and if so try to fix it.

Reference code (check if it works before porting)

Just for the protocol from Matrix:

Maybe it was caused by #1290
Anyway, it's not currently used iirc, except for a fallback method somewhere (maybe for age-restricted videos? AudricV probably remembers). But you never know, maybe we'll need to do a hotfix at some point where we'll need to temporarily switch to a different client that has n-params, and in that case it'd be good to have the code ready.

AudricV
Your guess is right, even if YouTube is testing a new player calling external functions in variables if I remember properly

So I guess this can be removed completely...
