Updated kaldi_io can not read from pipe (python3)

[KarelVesely84]

Hi, thanks for letting me know... After looking closer into it,
it seems that this will not be trivial to resolve...

In python3, the os.popen() supports only the transfers of utf-8 strings
(i.e. it does not accept the 'wb' mode of file opening only the 'r' mode,
which cannot be used to write the byte-strings b'...').

In python2, there was no such problem as the 'string' and 'byte-string' is the same type.
Do you know any clean solution? Or would it be fine to support pipe-ing just for python 2.x ?

Hi, finally I found a way how to support pipes both for pyhon2 and python3. Let me know, if there are some more problems... K.
