This patch adds a new key definition KEY_EMOJI_PICKER and maps 0x0c/0x0d9 usage code to this new keycode. Additionally hid-debug is adjusted to recognize this new usage code as well.

Specifically, it is present in Apple Magic Mouse 2. In contrast, usage 00850064 is also the capacity in percentage, but is relative to full capacity.
