generates a predetermined set of files instead of outputting to its
standard output.

This removes all allocations in the `Scanner` code. The downside is that
the buffer is now stored in the `Scanner` structure, making it 48 bytes
larger. This however makes the code much more performant.

`self.buffer` is a `VecDeque<char>`, meaning that characters are stored
on 4B. When reading as we used to do, this means that every 1 byte
character we read was turned into 4 bytes, which was turned into 1 byte
in `String::extend`.
Instead of going through `self.buffer`, use a local `String` to store
the characters before pushing them to `string`.

Instead of doing a loop that goes:
* fetch from input stream
* push char into string
Make a loop that fetches characters while they're not a breakz and
_then_ extend the string. This avoids a bunch of reallocations.
