Support for Sub-Issue endpoints

[e7217]

Description

Hello,
There is no functionality in go-github to create, remove, or update Sub-Issues, so I would like to add this functionality.
Would it be okay for me to proceed with this?

Sure, @e7217 . It is yours.

I was just looking to see if these endpoints are directly supported and found this issue. @e7217 are you planning to solve this? I do not see an open PR for it.

@jsumners
I have another commitment, so I plan to proceed with this feature after that. If you need it sooner, feel free to proceed with the development of this feature. If you start the development, please let me know so that I don't duplicate the work.

In case of urgency, you can directly call the API for now.
Please refer to the information below:

@e7217 I am not willing to contribute code to Google unpaid. Take your time.

@jsumners - I let this go the first time I saw it but I would like to make one thing clear.

If you were to contribute to this repo, you would not be "contributing code to Google" any more than if you contributed code to any other repo, including https://github.com/fastify/fastify, https://github.com/pinojs/pino, and https://github.com/jsumners/alfred-emoji . Google has access to all these repos, and all their licenses allow them to use that code.

Instead, what you would be doing is contributing code to a repo that is owned by Google (and signing their CLA which I understand that many people do not want to do, which is fine) and is used by many people who find it useful.

You've made it very clear how you feel about Google. Please stop.

I answered a direct question posed to me with the reason I will not be taking up the call. It's unfortunate that you don't like that, but that's the way it is.

The code is owned by Google. Any contribution will be giving time and product to one of the wealthiest companies on the planet. I will not be doing that. The projects you linked that I am directly involved with are owned by the contributors, and thus not comparable to this project.
