Issue with Symbol and BigInt from JavaScript

See original GitHub issue

In the following Python code standard JavaScript primitive types (BigInt and Symbol) are missed:

from browser import document, console
import javascript

n = javascript.BigInt(2) # AttributeError: 'module' object has no attribute 'BigInt'
s = javascript.Symbol("abracadabra") # AttributeError: 'module' object has no attribute 'Symbol'

Below the Stacktraces for both this lines

Yes, it works:

from browser import window

symbol = window.Symbol("test")
assert symbol.description == "test"
