Add option to disable import sorting (for monorepo)

[foges]

Is your feature request related to a problem?
I have a monorepo and want to exclude sorting of a specific package (it's huge / legacy and I don't want to touch it)

Describe the solution you'd like
Add an option to disable this plugin via the prettier config.

Describe alternatives you've considered
Installing this plugin only in packages where I want it applied. I'd prefer to avoid this option since I want to create a set of global configurations in my monorepo.

Additional context
None.

*bump* could really use this as well.

I would also love this feature for my monorepo.
