Sorry it took so long.
I added two settings that disable trimming:

	// DisableMultipleDashTrim defines if multiple dashes should be preserved.
	// Default is false (multiple dashes will be replaced with single dash).
	DisableMultipleDashTrim = false

	// DisableEndsTrim defines if the slug should keep leading and trailing
	// dashes and underscores. Default is false (trim enabled).
	DisableEndsTrim = false
