--------------
- License updated to vanilla BSD 2-Clause to ease package use
(https://opensource.org/licenses/BSD-2-Clause).
- Test suite made discoverable by unittest/unittest2 discovery feature.
- Fix to decoder working on indefinite length substrate -- end-of-octets
marker is now detected by both tag and value. Otherwise zero values may
interfere with end-of-octets marker.
- Fix to decoder to fail in cases where tagFormat indicates inappropriate
format for the type (e.g. BOOLEAN is always PRIMITIVE, SET is always
CONSTRUCTED and OCTET STRING is either of the two)
- Fix to REAL type encoder to force primitive encoding form encoding.
- Fix to CHOICE decoder to handle explicitly tagged, indefinite length
mode encoding
- Fix to REAL type decoder to handle negative REAL values correctly. Test
case added.
