[bug#63512] [PATCH] gnu: emacs-ement: Update to 0.9.1.

[jgart]

Hi Andrew,

Thanks for merging that.

The update also fixes an annoying edge case bug I was experiencing from the 
upstream release version packaged in Guix which is documented here:

https://github.com/alphapapa/ement.el/issues/147

TLDR: ement would freeze up because Emacs does not support Microsoft ICO files 
at all and someone uploaded an ICO file for their matrix room avatar ;()

The fix was to warn when encountering an ico file in a matrix room and leave 
the room's avatar slot set to nil in the respective ement API code.

This ICO file in this one matrix room literally would freeze up Emacs 
completely because it didn't know how to handle it and would lock up.

all best,

jgart
