fix: correctly calculate resize metadata when given w & h

[nick-vincent]

Meant to fix #510

There is an additional case not being handled in resizeTransform: If both width AND height are given, but no aspect.

This case is a bit complicated, because the fit needs to be considered and possibly used to recalculate all the values:

(See Resizing images in the Sharp docs)

I couldn't find anything in resize.spec.ts testing the metadata, any pointers there?

For testing, I wonder if you could refactor out the code for calculating dimensions and then just test that part with a unit test.

[benmccann]

@nick-vincent this PR will need a rebase

[benmccann]

I think I found some additional edge cases, so I went ahead and merged this so that I can add tests for all of them together at once
