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

The RASN1::Model class is the entry point to create a parser/encoder.

Simple example:
From ASN1. definition:

  Record ::= SEQUENCE {
    id INTEGER,
    room [0] INTEGER OPTIONAL,
    house [1] INTEGER DEFAULT 0
  }

a model may be defined this way:

class Record < RASN1::Model
  sequence :record,
           content: [integer(:id),
                     integer(:room, implicit: 0, optional: true),
                     integer(:house, implicit: 1, default: 0)]
end

Then, parsing is as simple as:

record = Record.parse(der_string)
record[:id] # => RASN1::Integer
record[:id].value # => Integer

And encoding:

record[:id].value = 16_543_154
record.to_der # => String

Changes:

### 0.3.0 / 2017-08-10

* add ASN.1 types IA5Sring, PrintableString, NumericString and
VisibleString,
* add Model#[]= to directly set value of an element
* add Model#type and Model.type to mimic Types::Base API
* add Model delegation to its root element for unknown methods
* fix Types::Choice#parse! which did not return number of parsed bytes
