Add a resize preset "80%" - for resizing screenshot made on 125% scaled screens

Is your feature request related to a problem? Please describe.
If you have a high DPI monitor with 125% scaling, your screenshots will be 125% increased in size.
To reduce them back to 100%, you need to downscale them to 80%.
The current presets however doesn't offer such value:

Describe the solution you'd like
Option 80% would be great :)

Does other service/app have this feature?
Can't say, I'm only using sqoosh!

And to be completely future proof, adding presets also for 150% and 175% scaled monitors would be also nice.
You can compute it with this simple formula:

1e4/125=80%
1e4/150=66.66666666666667%
1e4/175=57.142857142857146%

Thank you!
