//|         The ``init_sequence`` is bitpacked to minimize the ram impact. Every command begins with a
//|         command byte followed by a byte to determine the parameter count and delay. When the top bit
//|         of the second byte is 1 (0x80), a delay will occur after the command parameters are sent.
//|         The remaining 7 bits are the parameter count excluding any delay byte. The bytes following
//|         are the parameters. When the delay bit is set, a single byte after the parameters specifies
//|         the delay duration in milliseconds. The value 0xff will lead to an extra long 500 ms delay
//|         instead of 255 ms. The next byte will begin a new command definition.
//|         Here is an example:
//|
//|         .. code-block:: python
//|
//|           init_sequence = (b"\xe1\x0f\x00\x0E\x14\x03\x11\x07\x31\xC1\x48\x08\x0F\x0C\x31\x36\x0F" # Set Gamma

//|
//|         The first command is 0xe1 with 15 (0xf) parameters following. The second is 0x11 with 0
//|         parameters and a 120ms (0x78) delay. The third command is 0x29 with one parameter 0xaa and a
//|         120ms delay (0x78). Multiple byte literals (b"") are merged together on load. The parens
//|         are needed to allow byte literals on subsequent lines.
//|
