Adding Adafruit Bluefruit to list of supported devices.

Also, creating list of supported devices.

Tried to run against my Adafruit Blulfruit Board. Find the device on USB but get "error: error while reading from serial port: Operation timed out" not sure whats wrong. Needs more investigation.

Getting a response from the Board: [13, 10, 119, 114, 105, 116, 101, 32, 116, 104, 105, 115, 13, 10, 48, 32, 91, 48, 46, 48, 48, 32, 109, 86, 93, 13, 10, 48, 32, 91, 48, 46, 48, 48, 32, 109, 86, 93, 13, 10] So the Error 'Operation timed out' seams to be a bit misleading.

Note that the Adafruit bootloader is a variation of the original nRF bootloader; their Python tool adafruit-nrfutil deviates from the upstream tool they forked. I don't know how large the differences are; they are large enough to not just be compatible; they may or may not be small enough that this tool might support both behind a switch.

My impression from playing around with the patches and the code is that those two are too far apart to warrant treatment with the same DFU tool; can't tell how far their MBRs and flash configuration formats are distinct.

I've opened an issue asking for clarification, but unless that is resolved quite positively, my guess for resolving this would need at least a different BootloaderConnection and main implementation (that may share some things, but differ eg. in that the adafruit seems to send end-of-frame before every message, something which is not too uncommin in SLIP but which the original nRF bootloader doesn't tolerate, at least not with the way this tool expects the responses).

I would be happy to see a fork of this crate, like adafruit-nrfdfu, but Ferrous Systems has no immediate need to support the Adafruit devices, only the nRF52840-Dongle that we use in our training.
