* Convert tabs to spaces

* Unlock on RESET keypress:
- Display unlock pattern
- Disable LED get/set functions
- Enable reset to bootloader function

* Reduce brightness of rainbow backdrop in unlock pattern

* Add hid commands for setting led matrix mode

This changes the color setting to not change the mode, and set the hue
and saturation for QMK effects.

* Fix `CMD_LED_GET_MODE`

* Add Levi's Launch layout

* Fix layer mistake in Levi's Launch layout

* Add matrix command

* Define default RGB matrix speed

* Add active_keys effect

* Move definition of RGB modes inside ifdef testing for custom RGB modes

* RGB parameters per layer

* fix: Call `system76_ec_rgb_layer` after setting mode

* Include layer 3 and 4 in default layout for launch_1

I added support for layer 3 and 4 to the Configurator, but it seems to
load bogus values.

`dynamic_keymap_reset()` has a comment saying:
```
// Reset the keymaps in EEPROM to what is in flash.
// All keyboards using dynamic keymaps should define a layout
// for the same number of layers as DYNAMIC_KEYMAP_LAYER_COUNT
```

Other keyboards seem to have default layouts that only list the first
two layers while setting `DYNAMIC_KEYMAP_LAYER_COUNT` to 4, but
whatever. This appears to make the Configurator behave as expected with
layer 3 and 4.

* Use EEPROM to store RGB parameters

* Add layer 2 and 3 to other keymaps

* Add LED_SAVE command

* Use eeprom_update_block to improve performance

* Revert "Configuration values for starting HSV and speed (#7740)"

This reverts commit de1f60fd370b4769336b8a707ee12657aee46412.

* Update launch_1 rules.mk for changes in Qmk

* WIP keycodes matching EC behavior

* Modify default layout to match design

* Apply updates to jeremy layout

* launch_1: Use `KC_NO` instead of `KC_TRNS` for default layout

* Revert "launch_1: Use `KC_NO` instead of `KC_TRNS` for default layout"

This reverts commit f71c5e7ac3cecbbb1a1f8934db1f329407fef041.

* Fix building bootloader

* Workaround for upstream orientation

* Custom USB IDs for USB hubs, disable USB hub feature controller

* Update Jeremy's keymap

* Update Levi's Launch keymap

* Update flashing instructions and rewrite layout design instructions

* Update README.md

* Add a system76_ec command to disable input events

For testing purposes.
