Missing support for libinput options

[JohnDowson]

Please fill out the following:

Sway Version:
1.10
libinput version:
1.27.0

Description:

1. attempt to use tap_drag or tap_drag_lock libinput options
2. reload config
3. get an error nagbar saying Unknown/invalid command 'tap_drag'

get_inputs does seem to know what those options are:

> swaymsg -t get_inputs --raw |  jq '.[] | select(.type=="touchpad").libinput'
{
  "send_events": "enabled",
  "tap": "enabled",
  "tap_button_map": "lrm",
  "tap_drag": "enabled",
  "tap_drag_lock": "disabled",
  "accel_speed": 0.0,
  "accel_profile": "flat",
  "natural_scroll": "disabled",
  "left_handed": "disabled",
  "click_method": "button_areas",
  "clickfinger_button_map": "lrm",
  "middle_emulation": "disabled",
  "scroll_method": "two_finger",
  "dwt": "enabled",
  "dwtp": "enabled"
}
