feat: add sections within reminder lists

[teobz]

Hi! Firstly, thanks for the work you've put into rem! I just wanted to add a suggestion for a feature i've been craving haha.

Problem

Reminders app lets you group reminders into sections inside a single list. Rem doesn't support this yet. Right now my options are:

• Create separate lists (which doesn't match how I think about my tasks)
• Use workarounds like priority flags
• Switch to the GUI to organise things properly

What I'd like

# Create a section in a list
rem section create --list "To-dos" "Personal"

# Move a reminder into a section
rem update <id> --section "Personal"

# List reminders in one section
rem list --list "To-dos" --section "Personal"

# Show all sections in a list
rem sections --list "To-dos"

# Rename or remove sections
rem section rename --list "To-dos" "Personal" "Home"
rem section delete --list "To-dos" "Personal"

Just for reference, I'm sure you'd probably think of a nicer way to integrate these.

Thanks!

Thank you for using rem @teobz! I get it, I use sublists / sections a lot on Reminders app and this is definitely lacking on rem. When I was creating the CLI, the sublists were not exposed by Eventkit (Apple limitation). Let me see if I can find a workaround, I do not want to go ahead with private Reminderkit APIs :(
