Selection Prompt Search

[slang25]

This PR adds a couple of features to Selection Prompt:

• Search as you type
• Skipping selection of group nodes for Leaf selection mode

I've yet to add the tests which is a bit naughty, but wanted to share what I have so far to start some discussion. Is this feature welcome, or is there a better direction?

[slang25]

This is somewhat related to #1258, as this is a feature I'd really like in my CLI, however my only feasible options are to fork the library or hope I can get this merged.

This looks incredibly helpful - I'd love to see this merged soon.

[slang25]

Thanks @GOATS2K, I'm pretty happy with it and am using it in one of my apps. I've just updated the API names to be a bit more sensible.

@patriksvensson what are your thoughts on this?

[slang25]

@patriksvensson thanks for taking a look, I've addressed the feedback. I've added some tests, I could add some Verify tests too and cover more scenarios but am on the fence, let me know what you think.

[slang25]

Hi @patriksvensson, please could you take another look at this PR when you get some time. I'm happy to address any further feedback 🙂

Would love to see this go through soon, extremely useful feature when dealing with large prompts.

@slang25 I'm rebasing this and fixing the merge conflicts right now

[patriksvensson]

Merged! Thank you for your contribution. Much appreciated! 👍

Thanks @patriksvensson, this library is such a gem for the .NET community, I hope you have time to keep it going 🙂 I was worried we'd lose you to swift 😅

[patriksvensson]

@slang25 Haha, thanks! I still have a lot of love for dotnet 🙂
