TextBufferKit - a port of the vscode-textbuffer code to Swift 5.1

(This currently requires Xcode11 to build)

Documented here:

Based on the code here:

https://github.com/Microsoft/vscode-textbuffer

Plus the VSCode extensions, that include a higher-level API, and the text matching:

One significant difference from the original implementation is that this uses bytes rather than characters for storage, so it is necessary to create strings and characters out of the UTF8 representation.xs
