encoding: avoid quadratic time complexity when json-encoding non-UTF8 strings
Apparently the code uses "+=" with a bytes object, which is linear-time, so the
whole encoding is quadratic-time. This patch makes us use a bytearray object,
instead, which has a(n amortized-)constant-time append operation.
The encoding is still not particularly fast, but at least a 10MB file
takes tens of seconds, not many hours to encode.
