Description
I have a minor hassle when adding new tests and running
```
--mpl-generate-path=tests/baseline
```
I overwrite all existing baseline images in my repo. I then have to sort through which are added, because usually the regenerated old tests are still the same visually, but are not identical hash-wise.
I would propose adding a
```
--mpl-generate-missing=tests/baseline
```
Which would only generate new figures if the baseline is mising.

Research direction
Start by tracing how --mpl-generate-path=tests/baseline is handled and where baseline figures are generated. Compare that flow with the proposed missing-only behavior; done means existing baseline images remain unchanged while missing figures are generated in the specified path.
