Module domain::utils::base64

Decoding and encoding of base 64.

The base 64 encoding is defined in RFC 4648. There are two variants defined in the RFC, dubbed base64 and base64url which are differenciated by the last two characters in the alphabet. The DNS uses only the original base64 variant, so this is what is implemented by the module for now.

The module defines the type Decoder which keeps the state necessary for decoding. The convenince functions decode and display decode and encode octets, respectively.

Decoding currently requires the bytes feature as it is intended for use by the master file parser. This will change when the parser will be converted to work with any octets builder.
