Interp static local var breaks backwards compatibility with haxe 4.2 #161

Flixel CI (haxe 4.2, html5) is getting an error at Interp.hx:63:

/home/runner/haxe/haxelib/hscript/git/hscript/Interp.hx:63: characters 4-10 : Expected }

If hscript wants to officially stop supporting 4.2, HaxeFlixel will likely follow suit, but this is a pretty easy fix. I can create a PR sometime today
