Update for .Net 8 or .Net 9 and Flic2Lib 1.4

[breynolds]

I am developing an app that would use a Flic 2 and would like to use Maui. Any interest in updating your project? If not, I'll need to figure out how to do it from scratch.

I no longer possess a flic 2 button and as such not interested.

Feel free to create a PR or fork😃
