* Update keyboards/bm16s/bm16s.h

Co-Authored-By: bontakun <ben@bontakun.net>

* Cleaned up a bunch of unneeded stuff.

* Made layout name match.

* Changed rules file to have correct bootloader and indention. Updated readme to reflect availability on krepublic. Updated keymap to have more obvious RGB controls.

* Removed unnecessary file.

* Fixed grammar in readme.

* Migrated to autogenerated layout config, without issue.

* Renamed LAYOUT to match community standards.

+# bm16s
+
+A 16-key macropad, with USB C and per-key RGB backlighting. This is a variant of the BM16A, but with low profile Choc switches.
+
+Keyboard Maintainer: QMK Community  
+Hardware Supported: The PCBs, controllers supported  
+Hardware Availability: [KPrepublic](https://kprepublic.com/collections/pcb/products/bm16s-16-keys-custom-mechanical-keyboard-pcb-plate-programmed-numpad-layouts-qmk-firmware-with-rgb-switch-leds-choc-switch); [AliExpress](https://www.aliexpress.com/item/bm16s-16-keys-Custom-Mechanical-Keyboard-PCB-plate-programmed-numpad-layouts-qmk-firmware-with-rgb-switch/32999247908.html); [Massdrop](https://www.massdrop.com/buy/78169)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make bm16s:default
