Support yMinWarn, yMaxWarn, etc in Autoplot

[jbfaden]

Chris would like to support yMinWarn, yMaxWarn, etc in Autoplot. These are seen by the old das2stream parser but are not propagated to the QDataSet result. He has:

• yNominalMin
• yWarnMin
• yScaleMin
• yValidMin

Also this needs to be in the new das2stream parser. I also noticed that the d2s source appears to use the old das2stream parser.

Here's a Das2Server URI that should show this:

vap+das2server:https://space.physics.uiowa.edu/das/stream?mcp_hv&dataset=TRACERS/TRACERS-2/QL/ACE/HSK_Analog&useOldD2sParser=T&start_time=2025-08-31T23:28:00.000Z&end_time=2025-08-31T23:40:00.000Z

The new parser has this, but needs more verification. Also With the above URI, I notice that it refuses to use the scale specified, presumably because of logic that ignores invalid ranges. (Will look into this...)

The next devel release (20250207a) will use this metadata. Also since HugeScatter is often used for these large datasets, I made it show the bars as well. (TODO: get rid of huge scatter)
