Added tag color support for cards

[abasse]

This pull request introduces tag color support for cards, similar to the functionality in Google Keep. Users can now configure colors for each tag in the plugin settings, enhancing the visual organization of their notes and tasks.

Feel free to reorganize the code if you find any areas that could be improved.

Thanks for the great plugin!

Wow, that looks beautiful, after a few more improvements in this plugin, I don't think I will ever have to get back to Google Notes again. Looking forward to get this merged with the plugin and see the next version.

Unfortunately, it seems that the author has no interest in merging the PR.

Can't comment on that, but there are days we all do get occupied with few other areas of our life. At present I got so many new ideas to implement in this plugin and optimize performance, but getting hold back due to some personal reasons.

But @jillro, it would be nice if you could update us with the current dev status of this plugin and what are your thoughts on this PR?
