## Description

Based on #179 

This moves the QuicFrame generation into the `qlog` module. The public
interface for recording frames in sent packets now either takes a
`crate::Frame`, or for frame types where constructing such a frame would
have a cost, there's a specialized method on the `QlogSentPacket`.

This keeps the mapping between frames and `qlog::QuicFrame` localized
instead of spread out through the crate, and will make it much easier to
add support for more frames.
