### Is your feature request related to a problem? Please describe.

Try to view, edit or convert `.ICO` files from Windows 1.x/2.x.

http://fileformats.archiveteam.org/wiki/Windows_1.0_Icon

Sample file: CARDFILE.ICO opened by ICONEDIT.EXE:

![CARDFILE ICO-SCR](https://github.com/ImageMagick/ImageMagick/assets/8339596/86f4c173-e465-49d1-a306-accca4a02cda)

The data are the black&white pixels, the grey zones are believed to be transparent.

The icon of the program CARDFILE.EXE (CARDFILE.ICO) can be seen in the taskbar, bottom left, when CARDFILE.EXE is minimized:

![CARDFILE ICO-MINIMIZED](https://github.com/ImageMagick/ImageMagick/assets/8339596/5189ff55-892a-4e28-8adf-0b2841566f66)

and sometimes in the About dialog, specially in Microsoft programs:

![CARDFILE-ABOUT](https://github.com/ImageMagick/ImageMagick/assets/8339596/c832b2d9-e849-4d69-bbf2-dff35be75341)

According to this website, 1.x and 2.x share same icons:

Current output:
```
$ convert CARDFILE.ICO CARDFILE.PNG
convert: improper image header `CARDFILE.ICO' @ error/icon.c/ReadICONImage/233.
convert: no images defined `CARDFILE.PNG' @ error/convert.c/ConvertImageCommand/3354.
```


### Describe the solution you'd like

Be able to convert from and to ICO file format (Windows 1.x/2.x). For example from and to PNG.

### Describe alternatives you've considered

GIMP doesn't have support for it yet:
