[x3d-public] FreeWRL: I'm not sure what the standard says, but consider enabling ECMAScript's "let" in FreeWRL

[GPU Group]

Most recent duktape doesn't support "let" although some of duktape's
developers have tinkered with it.
https://github.com/svaarala/duktape/issues/2000
Most recent libmozjs / spidermonkey does / should support let:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/let

x however freewrl uses an older libmozjs 24, versus most current is over
100.
x last time I tried to build libmozjs on windows I gave up
