RASN1 is a pure ruby ASN.1 library. RASN1 helps to create ASN.1 parsers  
and encoders.

Changes:

### 0.9.0 / 2021-12-27

\* API break: Types::Base#initialize needs `:value` option to set a value. Setting a value as first argument is no more supported.  
\* Types::Base#inspect: add information about ASN.1 class and about tagged value.  
\* Types::Base: change how type without set value is handled internaly. Add #void\_value to define 'value' when no value is set (to always have a well-defined type).  
\* Model: use a private class Elem instead of an array to define model's root.  
\* Model: simplify code.  
\* Types::Integer#enum is always a Hash.  
\* Fix Types::Utf8String#der\_to\_value by setting @value.  
\* Fix some minor issues due to type handling (Types::Base, Types::BitString, Types::GeneralizedTime, Types::ObjectIf, Types::Sequence and Types::SequenceOf)  
\* Types::Constructed#inspect: always show optional fields
