Version of readProcessWithExitCode that uses lazy bytestrings instead of strings and allows setting environment variables.

readProcessWithExitCode creates an external process, reads its standard output strictly, waits until the process terminates, and then returns the ExitCode of the process and the standard output. stderr is inherited from the parent.

If an asynchronous exception is thrown to the thread executing readProcessWithExitCode, the forked process will be terminated and readProcessWithExitCode will wait (block) until the process has been terminated.
