Add three new helpers to the existing progresstracking package:
- Ticker: spawns a 1 Hz goroutine that calls a report function with
the current value of an atomic counter and a total. Returns a stop
function (safe to call multiple times via sync.OnceFunc) that fires
one final report and blocks until the goroutine exits.
- NewWriter: wraps an io.Writer and calls onProgress at most once per
interval with the cumulative byte count.
- CountingWriter: an io.Writer that atomically counts bytes written,
for use with Ticker.
These will be used by the appliance flash and OTA update code in
subsequent commits.
