Separate mousewheel-scroll setting & add secondary zoom method

[themoenen]

Is your feature request related to a problem? Please describe.
Zooming in and out can only be done with the mousewheeel. This can be disrupting to the scroll experience.

Describe the solution you'd like

1. Allow user to disable mousewheel zoom without also disabling pinch-to-zoom
2. Provide a secondary method for zooming that doesn't involve the mousewheel, e.g. ctrl-drag

@themoenen , I was unable to replicate the reported bug while testing Miew in both TypeScript and TypeScript with React applications. It seems that the any type for options in the Miew constructor is enough to avoid any errors.

Could you please provide more details about your specific setup, including the version of Miew you're using, any relevant code snippets, and the exact steps to reproduce the issue? This information will help us narrow down the potential causes."

I think this was supposed to be in response to #559. I will answer over there.
