Autoplot release v2026a_7

[Jeremy Faden CS]

I've made a new production release of Autoplot, v2026a_7.  This is
mostly bugfixes, like:

* correction to PDS3 fill values, when NaN is used as fill.
* PWD in remote .jyds scripts was the download directory, not the https
site, so adjacent calibration file was not loaded.
* FFTPower of X component of a vector dataset would incorrectly reset.

and new features like:

* Automatically remove spaces in "https : //..." to thwart Outlook
email's URL mangling.
* vap+inline URIs with one getDataSet call now support Tools->"replace
file" action.
* add completions for each enum of getParam in Jython script, and also
use examples.
* add routines for realPart and imaginaryPart to make Jython codes more
deliberate.

This is the production version at https://autoplot.org/latest/. Enjoy!
