chore(logging) Add loop speed logs

[dfulu]

Changes in this Pull Request

This PR adds a line to the logs which is something like

2026-01-12 14:33:50 INFO     83.33% progress through time range. 0.89 seconds/image. ETA 0:00:10.724019

On the main branch we do have the % progress, but this PR adds the seconds/image log and the estimate time to remaining/

The seconds/image is done using an exponential moving average (EMA) which was largely taken from tqdm. The ETA uses the EMA and assumes that all images between the current one and the end of the time range will be available and that the process continues at the current speed.
