Autoplot production release v2026a_6

[Jeremy Faden CS]

I've updated the production release of Autoplot.  It's mostly bug fixes,
including:

* ASCII data source's where not equal (where=param.ne(0)) control was
incorrectly coded.  Thanks, Sadie!
* Series Renderer automatic data reduction did not draw extent of data
within a pixel column.  Thanks Jaya!
* 1D and 2D binAverage routines would include data outside the range in
minimum or maximum bin.

There are a couple of noteworthy new features, like:

* Reading IDLSaves with 64-bit ints in a variable with name containing
epoch is assumed to be CDF_TT2000 timetags.  Thanks, Dave!
* formatDataSet/export will create folders when they don't exist
already, matching logic used every where else in Autoplot.
