[manually-flashing] merge with mrchromebox site

[player-k12]

fixes #131

[player-k12]

let me know if anything isn't up to standard or needs to be changed

[player-k12]

I was unsure about whether to use mrchromebox's flashrom or to keep the old one
I can also copy over the HWID preservation for the unbricking sections

I don't know if the futility command is the same as gbbutillity, I can't run it on my computer.

What are you trying to run and what is the issue?

(Also, gbbutility is deprecated and is literally a symlink to futility now)

I was trying to test futility but I'm on Ubuntu 22.04 and I don't have libzip5. I have only used mrchromebox's gbb utility binary so I don't know the command to extract the HWID with futility

[WeirdTreeThing]

Basically, any gbbutility command will now start with futility with the rest of the command added as is.
For example, gbbutility --get --hwid somefile.rom now becomes futility gbbutility --get --hwid somefile.rom.
futility just combines mulitple utilities (gbbutility, vbutil_kernel, etc) into one binary.
