About Your Setup

How many devices are detected?: 11
Mobile App Version(Not required): (latest version of the "new" smartthings app)
SmartApp Version: 2.3.4
Device Handler Version: default? Idk, it's not a custom handler.
Homebridge Version: 1.1.1
NodeJS Version: 12.16.3

Expected Behavior

Tell us what you think should be happening

Devices using the "Z-Wave Fan Controller" device type and selected as a "3 speed fan" in the homebridge-smartthings SmartApp should show as having 4 options in Home - OFF, LOW, MED, HIGH.

Current Behavior

What happens instead of the expected behavior?

Currently, although the fan shows as having OFF-LOW-MED-HIGH options within the native SmartThings iOS app, it shows as a dimmer-style infinitely-adjustable scale from 0-99 in Home app. When off, it shows 0. When on LOW, it shows 33. When on MEDIUM, it shows 66. When on HIGH, it shows 99.

I don't want to have to tell Siri "set the fan to 66%" to put it on Medium.

Steps to Reproduce (for bugs)

Provide a link to a live example, or an unambiguous set of steps to reproduce this bug. Include code to reproduce, if relevant

Add a z-wave fan switch to smartthings (I am using the "GE Enbrighten Z-Wave Plus Smart Fan Control, Works with Alexa, Google Assistant, 3-Way Compatible, ZWave Hub Required, Repeater/Range Extender, White & Light Almond, 14287")
SmartThings automatically selects the "Z-Wave Fan Controller" device type.
Within the SmartThings App, you can control the fan using OFF-LOW-MED-HIGH options as expected.
Select the new z-wave fan as a 3-speed fan within the homebridge SmartApp.
The new fan appears in Home app, but shows the current speed as 0%, 33%, 66%, or 99%.

Context

How has this issue affected you? What are you trying to accomplish? Providing context helps us come up with a solution that is most useful in the real world**

I just want to be able to tell siri to set the fan to LOW or MEDIUM or HIGH, which are the correct native speed designations for this device.
