Changelog entries for abTEM#563 (PRISM exit planes, ensembles, single positions)

[pzeiger]

Changelog entries for abTEM#563, which is still open and stacked on abTEM#556. The changelog lists only changes that are merged into dev, so this should merge after abTEM#563 does.

Entries

• Performance: one bullet, at the end of the section. The automatic PRISM batch sizes now count the exit planes, and the bullet gives the peak-memory figure from the PR (9 exit planes, 128 x 128 grid). The PR description reports 9249 MB before and 1284 MB after, rounded here to 9.2 GB and 1.3 GB.
• Bugfixes: one bullet with a sub-bullet per fix, as in Changelog entries for abTEM#556 (seven fixes, two changes in results, CPU–GPU arithmetic) #38, at the end of the section. The behaviour change comes first and starts with Behaviour change:. It covers PRISM reduce without a scan, and a single (x, y) position, which return no position axis; this answers point 4 of the abTEM#563 review. The other sub-bullets cover the exit-plane axis, eager WavesDetector over FrozenPhonons(ensemble_mean=True), and transition_potential_scan with upsample=True.

The Bugfixes section ends at the same place in #35, #36, #38 and #39, so whichever merges later needs a trivial rebase of the insertion point.
