[Keyboard] PloopyCo update and fixes (#10936)

This is based on feedback talking with crop_octagon about the device.  Future trackballs will ship with ATMEL DFU for simplicity.  This also includes some fixes and optimizations based on code review and tinkering on my own devices.

 The `PLOOPY_DPI_OPTIONS` array sets the values that you want to be able to cycle through, and the order they are in.  The "default" define lets the firmware know which of these options is the default and should be loaded by default. 
 
 The `DPI_CONFIG` macro will cycle through the values in the array, each time you hit it.  And it stores this value in persistent memory, so it will load it the next time the device powers up.

-# Programming QMK-DFU onto the PloopyCo Trackball
-
-If you would rather have DFU on this board, you can use the QMK-DFU bootloader on the device.  To do so, you want to run: 
-
-    make ploopyco/trackball:default:production
-
-Once you have that, you'll need to [ISP Flash](https://docs.qmk.fm/#/isp_flashing_guide) the chip with the new bootloader hex file created (or the production hex), and set the fuses:

-| Fuse     | Setting          |
-|----------|------------------|
-| Low      | `0xDF`           |
-| High     | `0xD8` or `0x98` |
-| Extended | `0xCB`           |

+
+If you would rather have DFU on this board, you can use the QMK-DFU bootloader on the device.  To do so, you want to run:

+| Extended | `0xFE`           |
+
+If you're using QMK DFU, you'll also need to add `BOOTLOADER=qmk-dfu` to your keymap's rules.mk file, to ensure that the reboot/reset works correctly. Otherwise, it will jump right back into the firmware, like nothing happened.
+
+Additionally, once you've flashed the qmk-dfu bootloader onto your device, you will no longer be able to use the Arduino IDE to flash the board. You'll need to use the command line or QMK Toolbox to flash it.
