Currently we only have a immutable buffer implementation (`Buffer`). To implement various array builders, it's better to also have a mutable version of this so that we can keep appending data to a buffer. This PR adds a `MutableBuffer` struct which is growable and can be mutated. A mutable buffer can also be consumed and converted into a immutable buffer.
