fix: improvements across the board

* Update README.md, make sure the disclaimer is seen before install instructions.
* update ustorage to have temp readings on some samsung ssds (stupid samsung)
* Patch and support ulcmd relying on output from ubnteeprom
* Move away from ubnthal FINALLY now that we patched ulcmd (hacky but works!)
* added README.md to ubnteeprom, since I expect at somepoint folks will fork/use it for other projects.
* Added our own kernel module to force mtd's RO, which does a better job than ubnthal did :)

+# mtd-lock
+
+A stupid basic kernel module to ensure we set /dev/mtd as RO (fully) in our firmware. This is done to prevent users/bad actors from wiping your bootloader/Unifi EEPROM, which are required for your device to function!

+# ubnteeprom
+
+A userspace tool to parse/read/render the EEPROM MTD partition on Unifi UNVR/UNVR Pro, and possibly other Dream Machine devices in the future.
+
+## Purpose
+
+This tool was created as a userspace replacement for the functions Unifi's ubnthal proprietary kernel module provides, by reporting most of the same information out as `/proc/ubnthal/*` as well as some output from `ubnt-tools id`.
+
+The idea behind this is so we can get this repo off of using proprietary Unifi code as much as possible, so replacements for things are required. All code for this was reverse engineered and no unifi proprietary code was copied/used in the creation of this tool.
+
+## Usage
+
+Get similar output to `/proc/ubnthal/board`:
+
+    ubnteeprom -board
+
+Get similar output to `/proc/ubnthal/system.info`:
+
+    ubnteeprom -systeminfo
+
+Get similar output to `ubnt-tools id`:
+
+    ubnteeprom -tools
+
+Get a specfic value for a selected key in output, for example, `boardid`:
+
+    ubnteeprom -board -key boardid
+
+## Building
+
+```
+env GOOS=linux GOARCH=arm64 go build -ldflags="-s -w" -o ubnteeprom main.go
