py-asn1: updated to 0.4.5

Revision 0.4.5:
- Debug logging refactored for more efficiency when disabled and
  for more functionality when in use. Specifically, the global
  LOG object can easily be used from any function/method, not just
  from codec main loop as it used to be.
- More debug logging added to BER family of codecs to ease encoding
  problems troubleshooting.
- Copyright notice extended to the year 2019
- Fixed defaulted constructed SEQUENCE component initialization.
