Just noting here that I'm not planning to touch this during my sweep of the utils.

I'm going to action this, with the plan to retain both: `align_single_frame` & ` _intensity_peaks_image_single_frame` for now. I may well place this functionality elsewhere (with deprecation warnings). Hopefully getting to...

Much of this was done in #1040, but I think we could do with another loop around, so will leave this open.

~#1020 didn't update the changelog. Will sweep this up when I do the next batch of utils.~ Done.

### What's left? - take `signal` private (as `_signals`) - Deprecate all functionality in [radial_utils.py](https://github.com/pyxem/pyxem/blob/main/pyxem/utils/radial_utils.py) see #1002 - Rename the module [expt_utils.py](https://github.com/pyxem/pyxem/blob/main/pyxem/utils/expt_utils.py) - Bring dummydata into utils (#1049) ### No...

> @pc494 What do you think about trying to push for the 0.18.0 release soon. What is still needed to be done (besides the large and daunting [pyxem/diffsims#201](https://github.com/pyxem/diffsims/pull/201) (and #1018)...
