Cannot set asset_sender on an inner transaction AssetTransfer to do a clawback operation

[SilentRhetoric]

Subject of the issue

It is not possible to set the asset_sender transaction field when building an inner transaction asset transfer. This is required to perform a clawback operation on an asset.

Steps to reproduce

        itxn.AssetTransfer(
            xfer_asset=self.token_asset_id,
            asset_amount=1,
            sender=Global.current_application_address,
            asset_sender=Global.current_application_address,  # Unexpected keyword argument "asset_sender" for "AssetTransfer"
            asset_receiver=Txn.sender,
            fee=0,
        ).submit()

Expected behaviour

The AssetTransfer class, as well as the more generic InnerTransaction class, should provide a way to set asset sender per the clawback transaction specification at https://developer.algorand.org/docs/get-details/transactions/transactions/#asset-clawback-transaction.

Actual behaviour

Mypy identifies the missing kwarg (Unexpected keyword argument "asset_sender" for "AssetTransfer"). The contract will also fail to move a frozen asset because it needs the inner transaction to have this field set.

This should be fixed in the next release which will be out this week, in the mean time, since in this case the compiler actually supports this and it's just missing from the stubs, the following is a viable workaround:

        itxn.AssetTransfer(
            xfer_asset=self.token_asset_id,
            asset_amount=1,
            sender=Global.current_application_address,
            asset_sender=Global.current_application_address,  # type: ignore[call-arg]
            asset_receiver=Txn.sender,
            fee=0,
        ).submit()
