Creates/updates a data/binkstats.ini file which tracks BinkIT/BinkP session
statistics:
- inbound successes/failures (per node)
- callout successes/failures (per node)
- totals (per node)

It's a human-readable data file (in .ini file format), so it's pretty
self-explanatory.
The [callout success: <address>] sections provide details about the last
successful outbound BinkP session with the specified node.
Similarly, the [callout failure: <address>] sections provide details about the
last *failed* outbound BinkP session with the specified node.
And there are very similar sections for successful and failed *inbound*
sessions as well.
The [totals: <address>] sections track running totals for each node as well.
