Add Select Menu Disabling

[Conch]

I noticed that the official Discord API select menu docs have the option for disabling the menus, yet this isn't an option in Dislash.py. I'd appreciate it if it was a thing, it'd make some stuff so much easier, such as timeouts or after selection.

Seems like they added this field later
Thanks for sharing this, I'll add this asap
