Is it possible to move away from V8 in favor of a liter dependency? Say, QuickJSR

@jtextor V8 is a very heavy dependency to build and it is broken for some platforms. Could we get rid of it? Possibly, replacing with QuickJSR, like rstan did?

It's an interesting idea, but V8 is very fast and QuickJS seems to be quite a bit slower ... I don't know if that would be a bottleneck or not? Could be an interesting thing to test.

I cannot vouch personally for speed (since V8 is broken for the platform where I test), but given that rstan uses QuickJSR, and rstan is a very sophisticated and speed-wanting software, it should be pretty good.

QuickJSR itself builds quickly, and Stan models work fine. V8 – well, last time I tried to fix it, and went pretty far with that, it took multiple hours before failing on a wrong assembler :) Admittedly, my PowerPC is no TALOSII, but it is a very heavy dependency.

@jtextor Maybe you could make a branch with a switch to QuickJSR? That would fix dagitty without compromising it for those preferring V8.

@jtextor Any update on this?
