The session metadata is provided all at once when a new bsr is opened.
While the session recording metadata records metadata about a recording
while the recording is happening, notably it records each time a new
connection occurs.
The nested structure of the session metadata does not lend itself to the
append-only syntax of the recording meta file. In addition we do not
want to mix different kinds of metadata together. Thus the session
metadata is now written to a separate file in the BSR, and is written as
JSON which better handles the nested structure and allows for simpler
encoding/decoding.
Similarly the summary files are intended to be written to as containers
close and have been switched to JSON.
