Stub import doesn't work

[marco-prontera]

When I use the stub by following the documentation with:
import * as cmpstub from "@iabgpp/stub";
then execute:
cmpstub();
I receive errors relative to the stub module code that does not provide an export named 'default', so it can't be used in a esm context.
I think a solution can be to follow the tcf stub module code and config that works well on old and recent projects: https://github.com/InteractiveAdvertisingBureau/iabtcf-es/tree/master/modules/stub

@chuff can you take a look at this one?

I also tried following the documentation for this library (https://github.com/IABTechLab/iabgpp-es/blob/master/modules/stub/README.md) and it doesn't work. You definitely can't use import * as cmpstub.

The README should be updated to tell implementers that they should be making a copy of stub.js themselves, shouldn't it?
