Error when enabling Razer Blade 15 keyboard

[Rakin Ishraq]

When I enable "Razer Blade 15 (2021 Base)" in the Settings and try to connect to the OpenRGB server, it raises an error as soon as I try to initialize with OpenRGBClient("127.0.0.1", 6742).

Traceback (most recent call last):
  File "C:\Python39\lib\site-packages\openrgb\network.py", line 137, in read
    self.callback(device_id, packet_type, utils.ControllerData.unpack(data, self._protocol_version))
  File "C:\Python39\lib\site-packages\openrgb\utils.py", line 547, in unpack
    metadata = MetaData.unpack(data, version)
  File "C:\Python39\lib\site-packages\openrgb\utils.py", line 489, in unpack
    serial = parse_string(data)
  File "C:\Python39\lib\site-packages\openrgb\utils.py", line 116, in parse_string
    return parse_var(f'{length}s', data).decode().rstrip('\x00')
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte

The above exception was the direct cause of the following exception:

Looks like another #33. What version of OpenRGB are you using?

I was using 0.6 and after updating to 0.7, I can initialize properly but still get an error:

Traceback (most recent call last):
  File "C:\Projects\Python\prisma\rgb.py", line 59, in <module>
    rgb_keyboard("#ff0000", "#ffffff", "#00ff00")
  File "C:\Projects\Python\prisma\rgb.py", line 55, in rgb_keyboard
    keyboard.zones[0].set_color(col3)
  File "C:\Python39\lib\site-packages\openrgb\orgb.py", line 85, in set_color
    buff = struct.pack("iH", self.id, len(self.leds)) + (color.pack())*len(self.leds)
AttributeError: 'str' object has no attribute 'pack'

The set_color function takes an RGBColor object as an argument, not just a string. It's an easy fix though. just change line 55 to

keyboard.zones[0].set_color(RGBColor.fromHEX(col3))

and make sure that you import RGBColor from openrgb.utils.

Ah, sorry about the silly mistake. Thanks for your time.
