PR for adding debounce. I implement some of ezButton's functions.

Hi Gerald, thank you for this PR.

Although this repository is very old, and I recognize that the code formatting is ugly, this is not how this issue should be addressed.

Please consider the following:

• You should not mix changes unrelated to the feature you want to merge in a PR
• You cannot enforce your own formatting changes without an agreement with the author
• You should have a clean commit history
• You should provide a rather verbose description in a PR with a problem statement and your solution

To make it easy on you, let me reformat the code first. Then, you can rebase and focus on the functionality you want to add.

Once again, thank you for the effort; I do appreciate your attention to detail.

I'm done with the reformatting; feel free to proceed.
