Can no longer download/install kindlegen

[waded]

README.md says "Kindlegen will be installed automatically" and "Kindlegen must NOT be in PATH, will be downloaded on install!" however that doesn't appear to work anymore. During npm install I see the error:

> [email protected] install
> node install.js

fail to download
/Users/x/kindle-periodical/install.js:19
        throw Error(err);
              ^

Error: HTTPError: Response code 403 (Forbidden)
    at /Users/x/kindle-periodical/install.js:19:15
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

It's my understanding Amazon replaced kindlegen with other software so perhaps this is not surprising.

Hi, yes youre right. Its replaced with kindlepreviewer` so it needs to replace with this ...
