multiple retentions in one file [BUG]

[dschmidt-itn]

If I have multiple different retentions (archives) in one file I can't get them to show together in one graph.
Is this normal or am I doing something wrong? Whisper-fetch also displays them wrong if I set a "--from"

Steps to reproduce the behavior:
whisper-resize $file 60s:5d 5m:30d 15m:365d 1h:5y

For example if I choose the retention periods above and I set a "--from=" with a timestamp from 7 days ago I only get values up until 5 days ago (the 5 minute-values) after that the graph just "stops" and whisper-fetch only shows "None"
But If I choose a start time from 3 days ago I get the correct values.

Environment (please complete the following information):

• OS flavor: Ubuntu 22.04
• Setup type: from OS packages
• Python 3.10.6
