SPM compatibility fixes, re-org: WIP

[DanBurkhardt]

Hi. I have forked your fork and done some re-organization and compatibility expansion. There are a lot of changes in the top-line numbers, but that is mostly due to having duplicated example projects. Mostly this is a deletion / re-organization effort because I like the FW and need SPM support.

This is a draft PR: I am opening this to see if you would like to merge the changes / support the direction I am taking this.

Here is the TL;DR:

• I re-implemented swiftPM compatibility because it was totally busted
• Fixed Package.swift: mostly cleanup but it would not build until I upped the swift tools version
  • not sure what was corrupted here, tbh.
• Replaced the Swift Package Manager + Example project workspace with a non-corrupted implementation
  • it would not even open with Xcode 14 👀
• created a new forked "Examples" directory so SPM and Cocoapods examples can co-exist
• updated the package name to reflect "ContainerController" without the Swift on the end (redundant)
• fully tested and all working properly with Swift Package Manager implementation

Cocoapods, however, still has some import issues, this is a WIP but will address in a subsequent push.

Options for fixing Cocoapods support without maintaining two example projects:

1. Leverage the working SPM directory path for all the files shared between the two projects. Essentially:

• delete all files from the cocoapods dir and pod deinit
• open the .xcproj file
• leverage the SPM implementation and re-import all files a relative path to the SPM directory

2. Move the files out of the SPM dir so they live in a 'shared' dir at the Examples/ folder level

• Then re-link all of the files in both examples using relative paths to the 'shared' dir

There is another issue: naming. Idk what the situation is on Cocoapods, but the name collision issues don't necessarily exist when using the framework via SPM because you pull it straight from the repo. As long as you don't use two packages of the same name. Anyway, will propose solution in a future update to the Cocoapods example-- curious to hear any opinions you may have as well of course.

Thanks a lot! Could you please sort out the conflicts so that we can consolidate it all?
