- This fixes BIT-1769 by logging all requests even in the absence of a
reply. The way that request and replying matching were being handled
was restructured to mostly ignore the transaction ids because they
aren't that helpful for network monitoring and it makes the script
structure more complicated.
- Add `framed_addr` field to the radius log to indicate if the radius
server is hinting at an address for the client.
- Add `ttl` field to indicate how quickly the radius server is replying
to the network access server.
- Fix a bunch of indentation inconsistencies.
