Allow setting pre- and post-contexts in `UnicodeBuffer` #85

Resolves #60.

Only dealing with the UTF-8 version for now. I personally need a UTF-16 version as well, but generalizing this for other encodings can come later.

FWIW, HarfBuzz API is designed so that when you are shaping a piece of text, e.g. a paragraph, you can itemize it then shape each item by passing the whole string and the item offset and length without having to split the string.

I understand. Lucky in Rust it's a very simple and safe operation.
