Allow plugin settings to govern dash behavior

[resignationinfinite]

A lot of people only use em-dash rather than en-dash, and most software including macOS converts two dashes to an em-dash rather than an en-dash. Please create a settings option to govern behavior so that those wishing to go with the more commonplace usage of two dashes to an em-dash can do so. Thanks for the great plugin!

Hi @KutuzovGambit the logic for dashes is like so:

Two dashes for en dash
Three dashes for em dash
Four dashes for three normal dashes (eg, ---)

I'll think about adding a setting to skip the en dash, though. Let me see how complex that would be and get back to you.

Ok, I've added a setting to skip en-dashes. This will only work with the latest insider build, though. Everyone should have access once live preview is released to the public.

Wonderful, thank you!!
