DSL-style macro for generating a serialization protocol message enum.

DSL:

/// [codec doc here]
codec $codec_name {
    /// [var doc here]
    $var_name($var_id) {
        /// [type doc here]
        $type_name.$type_idx: $type_ty,
    },
}

• $codec_name - camel-case codec enum name
• $var_name - camel-case variant/struct name
• $var_id - protocol variant identifier byte (u8) literal
• $type_name - snake-case type name
• $type_idx - zero-index type index in message array (usize)
• $type_ty - type rust type

E.G.:

/// My codec is awesome.
codec MyCodec {
    /// My codec has only one variant.
    MyVariant(0x00) {
        /// My variant has only one type
        my_type.0: String,
    },
}
