[Keymap] Update bcat's keymaps/userspace to share logic, add OLED functionality, and set up one of my macropads for WFH (#14702) * Add script to build all bcat keymaps at once * Move userspace RGB to separate source file * Move layer handling logic into userspace * Move keycap aliases into userspace * Add OLED userspace library and Lily58 OLED setup * Add Luna keyboard pet, generic OLED pet framework Luna artwork and original implementation by HellSingCoder, licensed under GPL v2.0. See also: https://github.com/qmk/qmk_firmware/blob/6dfe915e26d7147e6c2bed495d3b01cf5b21e6ec/keyboards/sofle/keymaps/helltm/keymap.c * Use OLED on bcat's Crkbd I had to turn off a few unused features to address firmware size limits. * Remove vestigial NK_TOGG keybindings * Add post-render hook to OLED pet API This enables OLED pets to draw custom widgets (e.g., LED indicator status) on top of their animation frames. * Add Isda keyboard pet For future use on my Unicorne keyboard. Unicorn artwork by sparrow666, licensed under GPL v2.0. See also: https://opengameart.org/content/unicorn-2 * Replace OLED timeout implementation with custom The default implementation never lets the OLED turn off if a continuous animation is in progress. The custom one does. * Move keyboard state for OLED functions into struct No change in firmware size, but makes keymaps read a little nicer and enables more functionality in OLED pets. * Enable continuously running OLED pet (for Luna) * Sync OLED state; enable Bootmagic only when needed The new extensible split transport for Split Common finally allows OLED on/off status to be synced between halves of the keyboard. :) Unfortunately, this required disabling Bootmagic Lite to keep my Crkbd under the firmware size limit. (I now after 28 bytes free on avr-gcc version 8.5.0.) So now I'll enable Bootmagic only on keyboards that actually require it, i.e., ones lacking an accessible reset button. * Update 9-Key macropad keymap for working from home * Remove includes redundant with quantum.h Co-authored-by: Drashna Jaelre <drashna@live.com> * Simplify BCAT_OLED_PET makefile logic * Swap some keys on my 9-Key macropad around * Inline spurious variable in OLED code * Remove max brightness that's now set by default The default max brightness is only 120 rather than 150, but that might actually fix some weirdness I've seen with bright white LED settings. * Enable specific RGBLIGHT modes instead of default The general trend these days seems to be enabling only the modes you want, so I'm manually expanding the ones currently enabled by RGBLIGHT_ANIMATIONS. I'd like to try out the TWINKLE mode too, but it seems not to work at all on ARM right now, and all my usable RGBLIGHT keebs are ARM boards. * Reenable RGB_MATRIX animations after #15018 My Crkbd still has a reasonable amount of free space with these: 27974/28672 (97%, 698 bytes free). The RGB_MATRIX_KEYPRESSES effects would put it over the firmware size limit, but I really don't ever use those anyway. * Use new get_u8_str function for WPM display Co-authored-by: Drashna Jaelre <drashna@live.com>
