Depend on pyodide-tblib instead of tblib

[hoodmane]

pyodide-tblib renders better location information than tblib.

With tblib

>   value = Square()["a"] + 1
E   TypeError: 'Square' object is not subscriptable

src/tests/test_fail.py:33: TypeError

With pyodide-tblib

    def test_partial_expression(selenium):
        class Square:
            pass
    
>       value = Square()["a"] + 1
                ^^^^^^^^^^^^^
E       TypeError: 'Square' object is not subscriptable
