[Feature Request]: Expanded overall support

[KC-2001MS]

It has been almost three years since this repository was last edited. During this time, Apple has announced new frameworks and libraries. In addition, new operating systems such as visionOS have been announced.
Therefore, we would like to see expanded support and updates using new frameworks and libraries in line with the current situation.

Update the frameworks according to the current situation as follows

• Add support for visionOS in Swift 5.10 or later to the Swift Package Manager
• Add DocC documentation using GitHub Pages and GitHub Actions
• Build/test/format with GitHub Actions
• xcworkspace file workspace with both package and demo app targets
• Localization on the package side (Japanese localization added)
• Demo app rewritten in SwiftUI

I am currently forking the repositories and implementing these in the expanding_support branch. If you would like, I will send a pull request.
Originally, I don't think it is desirable to implement these quantities and pull requests all at once, but I implemented them once because it is too much effort to repeat pull requests more than 5 times. I would be happy if you could take a look at it if you would like.
