generator: parser 1.0.2 incompatible with current generator

Describe the bug

Using parser 1.0.2 with generator 1.0.0-rc.13 results in errors:

Error: Parameter "asyncapiDocument" must be an AsyncAPIDocument object.
    at Generator.generate (/Users/david/projects/antora/extensions/asyncapi/antora-asyncapi/node_modules/@asyncapi/generator/lib/generator.js:154:64)
    at generate (/Users/david/projects/antora/extensions/asyncapi/antora-asyncapi/lib/antora-asyncapi.js:107:40)
    at process._tickCallback (internal/process/next_tick.js:68:7)

How to Reproduce

package.json:

    "@asyncapi/generator": "1.0.0-rc.13",
    "@asyncapi/parser": "1.0.2",

code:

      const parsed = await parser.parse(sourceString)
      const asciidoc = await generator.generate(parsed)

To see this in action, clone https://gitlab.com/djencks/antora-asyncapi, change the version of the parser to 1.0.2, run npm i, clone https://gitlab.com/djencks/antora-extension-examples, in antora-asyncapi change the location of @djencks/antora-asyncapi to the file system location, and run npm run clean-build.

Expected behavior

I expected my code to continue to work as you guys released upgrades.

I suggest that you have the generator export the parser it uses so I don’t have to try to keep versions in sync:

module.exports = Generator;
module.exports.parse = parse;

Then I can get the correct version of the parser easily without having to try to keep up with whatever you are doing.
