GET command does not work for feather52

[jerryneedell]

The get command does not work when accessing my nrf52 - feather52 board via ampy.

ls and put work, but no get

Note: this example includes PR #46 but the issues was also present without it.

jerryneedell@Ubuntu-Macmini:~/projects/feather52$ ampy -d 1.5 -p /dev/ttyUSB0  put test.py
jerryneedell@Ubuntu-Macmini:~/projects/feather52$ ampy -d 1.5 -p /dev/ttyUSB0  ls
test.py
my_scan.py
jerryneedell@Ubuntu-Macmini:~/projects/feather52$ ampy -d 1.5 -p /dev/ttyUSB0  get test.py

I guess the error message says it all:
https://github.com/adafruit/ampy/blob/master/ampy/files.py#L66
ties to use sys.stdout.write which does not exist on the nrf52 build

Hiya! We are discontinuing support for ampy, and will no longer be maintaining it. We are leaving this repository available for continued use. If you would like to take over supporting it, please contact us on the Adafruit Discord server and we can transfer the repository to you.
If you wish to continue developing it on your own, please fork the repository.

Huh, that looks weird, shouldn't there just be a print call instead? Can you try replacing sys.stdout.write with just print?
