Add code attempt input for IRIS Computer

[viral32111]

Proposed changes

• Add a wiremod input on the IRIS Computer for the GDO code attempt.

Explanation

This will allow buildiers to setup their own systems for properly verifying the code without using a custom E2 or wiremod contraption to do it. This would also pair nicely with the Transmit and Recieve inputs/outputs on the Stargates.

Evidence:

As far as I can tell, there's no input for this already. Only for:

1. Opening/closing the IRIS.
2. Setting the status that the GDO will respond with.
3. Setting the text that the GDO will respond with.
4. Enabling/disabling the auto-closing IRIS feature.
5. Enabling/disabling automatically opening the IRIS.
6. Setting the time in seconds for the IRIS to close after automatically opening.
7. Enabling/disabling menu interaction.
