Release 0.4.7

The major feature of this release is SET ... WITH COMPONENTS constraint support.

• Added WithComponentsConstraint along with related
  ComponentPresentConstraint and ComponentAbsentConstraint classes
  to be used with Sequence/Set types representing
  SET ... WITH COMPONENTS ... like ASN.1 constructs.

The other important change is that sizeSpec attribute of ASN.1 objects is now deprecated
in favor of uniform subtypeSpec, which is now used for all constraints.

• Deprecate subtypeSpec attributes and keyword argument. It is now
  recommended to pass ValueSizeConstraint, as well as all other constraints,
  to subtypeSpec.
• Added isInconsistent property to all constructed types. This property
  conceptually replaces verifySizeSpec method to serve a more general
  purpose e.g. ensuring all required fields are in a good shape. By default
  this check invokes subtype constraints verification and is run by codecs
  on value de/serialisation.

In the bug fixes department we have just one fix:

• Fixed a design bug in a way of how the items assigned to constructed
  types are verified. Now if Asn1Type-based object is assigned, its
  compatibility is verified based on having all tags and constraint
  objects as the type in field definition. When a bare Python value is
  assigned, then field type object is cloned and initialized with the
  bare value (constraints verificaton would run at this moment).
