Expected

I'd like to be able to just specify a type (eg. String), without making it an array String (eg. [String])

I'd like to be able to do:

const cli = cac('cli')
	.option('--size <size>', 'Size', {
		type: String,
	})

and get the parsed options:

{ '--': [], size: '16' }

Actual

Instead, I currently must do

const cli = cac('cli')
	.option('--size <size>', 'Size', {
		type: [String],
	})

and get the parsed options:

{ '--': [], size: ['16'] }

as communicated by the type:

cac/src/Option.ts

Line 5 in f51fc22

type?: any[]

Ah yes, I actually forgot why it was designed to be an array by default 😅
