Feature request: Allow building a version without 7Zip

[personalizedrefrigerator]

Joplin has an open issue related to including several default plugins with the application. One of these plugins would likely be Simple Backup, however, the 7Zip dependency seems to be causing MacOS signing issues (see laurent22/joplin#8040).

Would you be open to a pull request that

1. Allows building a version of the plugin without 7Zip
2. Uses the built-in CompressionStreams or Zlib APIs for compression when missing 7Zip
3. Either
   a. Uses the built-in Node or SubtleCrypto APIs for encryption (may be difficult for users to decrypt), or
   b. Disables the encryption option when missing 7Zip.

Thank you for developing this plugin!!

Joplin seems to already depend on 7Zip, so it might make more sense to instead expose 7Zip to plugins in the way that fs-extra is exposed to plugins.

I'm closing this issue for now — a new issue can be created after the plugin API exposes 7zip to plugins.

Edit: 7Zip is an optional dependency of joplin-desktop — I'm not sure whether it's currently being bundled and signed with the MacOS app.

I'm reopening this issue as per comment.

Closing as pull request will bundle 7Zip directly with Joplin (and allow requireing it from plugins.

Thank you again for this very useful plugin!
