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 :)
