[BUG] Lockstatus seems unresponsive

Describe the bug Using the code in the documentation I tried to get my keyboard to print some letters to the console when the lock status changes. However nothing seems to happen.

To Reproduce

pull master at commit 74db929

put the following code in code.py:


# in your main.py
from kmk.kmk_keyboard import KMKKeyboard
from kmk.extensions.lock_status import LockStatus

keyboard = KMKKeyboard()

class LEDLockStatus(LockStatus): def set_lock_leds(self): if self.get_caps_lock(): print("A") else: print("B")

    if self.get_scroll_lock():
        print("C")
    else:
        print("D")

def after_hid_send(self, sandbox):
    super().after_hid_send(sandbox)  # Critically important. Do not forget
    #if self.report_updated:
    self.set_lock_leds()

print("print test") keyboard.extensions.append(LEDLockStatus())


**Expected behavior**
Expecting the serial terminal to print either A or B depending on the capslock status.

**Debug output**
The serial terminal is working as it does print the "print test" text as can be seen below:

Auto-reload is on. Simply save files over USB to run them or enter REPL to disable. code.py output: print test

Code done running.

Press any key to enter the REPL. Use CTRL-D to reload.



**Additional context**
With some further testing it seems that the get_caps_lock() function only returns that the caps lock is not on even when it is. The module itself doesn't seem to hook into the HID stack properly?
