Ability to control the quality of the png export

[juanrgon]

Is your feature request related to a problem? Please describe.

Frustrated that I can't control the quality of the pngs that are exported when running:

npx slidev export --format png

Describe the solution you'd like

I would like to be able to control the quality via a feature flag of some sort

I think we could have an option to change the resolutions on exporting. PR welcome if someone wants to work on it

According to https://playwright.dev/docs/api/class-page#page-screenshot-option-quality, exporting in PNG format does not support the quality option (JPEG is OK):

Perhaps what @juanrgon needs is a feature to zoom in to make the exported image clearer.

update: See #1274

I think 1eaf92a (PR #1274) is what this issue requests. Close this for now.
