glue-jupyter marker control panel has arbitrary max size 10

[Jdaviz-Triage-Bot]

Reporter: pllim

Astrowidgets API allows Imviz to set marker properties (#662, #699), and theoretically, also arbitrary marker size. However, the control panel UI that comes with glue-jupyter has slider that stops at 10. This results in a bug in this workflow:

1. Display image in Imviz.
2. Use API to set marker size to 50.
3. Display some markers using that setting. They will appear in default viewer in size 10 instead of 50.
4. Create a new tiled viewer.
5. In new viewer, click Data and check the entry that corresponds to marker name to show markers. They will appear in size 50.

Why does glue-jupyter have a max value when Glue itself doesn't care?
