* Minor Changes

Minor changers per PR requests

* Minor Changes

Minor changes per PR suggestions

* Major Changes

Per PR suggestion from noroadsleft:

- changed macro to LAYOUT_all in info.json, dualsplit/keymap.c and ocm/keymap.c, and osa.h

- added osa.h macros for other layouts per suggestion and used suggested naming

-  changed naming of layout macros to correspond to macros and naming in default/keymap.c, dualsplit/keymap.c, ocm/keymap.c, splitbs/keymap.c, and splitrs/keymap.c

- removed duplicate layers from all keymaps and edited per suggestions

- compiled each keymap to check for and correct any potential errors. all compiled with no errors

* Minor Change

- fixed imgur image link in readme.md to be correct format

* Minor Changes

changes to macro layouts in osa.h
changes to dualsplit/keymap.c - added arrows to layer 1

* Changes

- Made changes to info.json to match osa.h
- changes to osa.c enabling indicator LEDs
- changed "dualsplit" directory name to "all" to match keymap naming in osa.h, info.json, and keymap.c
- minor changes to all/keymap.c

* Update keyboards/sck/osa/rules.mk

+
+About the OSA:
+
+The OSA was run as a private group buy of 20 units. It is an Alice layout keyboard based on the Open Source Alice files, altered by BlindAssassin111 based on input from the private group buy members.
+All case and other design files have been either reworked or created from scratch by BlindAssassin111. PCB was designed from scratch by BlindAssassin111.
+The OSA PCB is an ATMega32u4 powered, USB Type C, Alice compatible PCB and was created specifically for the OSA case, but with considerations to make it compatible with the Lubrigante acrylic cases (except for the Type C connector it should also be compatible with original TGR Alice cases).
+
+Keyboard Maintainer: [jrfhoutx](https://github.com/jrfhoutx)  
+Hardware Supported: OSA PCB by BlindAssassin111, ATMEGA32u4  
+Hardware Availability: Currently unavailable outside of the private group buy
+
+Make example for this keyboard (after setting up your build environment):
+
+    make sck/osa:default
+
