### Description Bumps both `STTextView` and `TextFormation` to their latest versions. This version of `TextFormation` changes how whitespaces are handled by filters, so there were some small modifications that needed to be made to accommodate. This also slightly adjusts the `DeleteWhitespaceFilter` to match other editor's functionality. `DeleteWhitespaceFilter` now deletes only the leading whitespace, and only to the nearest column, instead of just a number of spaces. It will also jump to the rightmost side of the whitespace when deleting. The other half of this PR is an implementation for undo/redo. This adds a `CEUndoManager` (with the prefix b/c AppKit declares that type) class that implements an undo/redo stack and operation grouping. It provides methods for performing undo/redo operations, registering text mutations from the editor, grouping operations, and clearing the undo stack. The class also automatically groups certain mutations. See the class documentation for more info there. ### Related Issues * Closes CodeEditApp#201 * Closes CodeEditApp#203 ### Checklist - [x] I read and understood the [contributing guide](https://github.com/CodeEditApp/CodeEdit/blob/main/CONTRIBUTING.md) as well as the [code of conduct](https://github.com/CodeEditApp/CodeEdit/blob/main/CODE_OF_CONDUCT.md) - [x] The issues this PR addresses are related to each other - [x] My changes generate no new warnings - [x] My code builds and runs on my machine - [x] My changes are all related to the related issue above - [x] I documented my code ### Screenshots https://github.com/CodeEditApp/CodeEditTextView/assets/35942988/35c64ed6-590d-493a-8f91-d918fef363a5
