Not working on Vim 9

[samuelps]

The plugin does not works on Vim 9 due an error in resize_mode#start function at line 3.
There is no highlight group named: Cursor

Thanks for reporting this! I wasn't aware it was possible for that highlight group to be missing — the :help lists it as a "default" group, and it's working fine for me in Vim 9 — but I've pushed a fix. If you get a chance, please do let me know whether this fixes the issue for you.
