chore: remove clone-buffer

[SourceR85]

This removes "clone-buffer" dependency.

Since Buffer.from is stable, there is no need for it.

small point, but should we maybe replace all instances of this with Buffer.from() just to remove one level of indirection

This will break pouchdb-utils/clone.js in browser engines.
cloneBinaryObject-browser.js is import-mapped to cloneBinaryObject.js, 'cause Buffer is a Node.js specific API.

If we want to unify it, we have to refactor towards ES standard ArrayBuffer/TypedArrays.
(shouldn't be part of this PR)

oops, makes sense!
