Error: reason='bad parameter: Other TypeError("argument \'data\': from_buffer() cannot return the address of a unicode object")'

I'm getting this error when trying to sign files using builder.sign_file in version 0.5.2. It works fine with version 0.5.0.

Error: reason='bad parameter: Other TypeError("argument \'data\': from_buffer() cannot return the address of a unicode object")'

Sorry about this. We changed the sign_ps256() function so that the second parameter now takes the key as bytes instead of a file path. So you have to load the bytes first and pass them to it. This made it more flexible for some environments, but we should have at least put in a better error and documented it.
