(possible bug) Some Android Ionic template resources are never generated

no matter what I try, I _cannot_ get `npx capacitor-assets generate --android --ios` to generate the following files from the assets I provide:

* `android/app/src/main/res/drawable/splash.png`
* `android/app/src/main/res/drawable/ic_launcher_background.xml`
* `android/app/src/main/res/drawable-v24/ic_launcher_foreground.xml`

these files came from the initially generated application folder, using the Ionic Angular `blank` template.

initially, my project `assets` folder contained the following files:

* `icon-background.png`
* `icon-foreground.png`
* `icon-only.png`
* `splash.png`
* `splash-dark.png`

I then went back to Figma, re-exported the exact same assets as SVG instead of PNG, replaced the files in my project `assets` folder, and regenerated all Android and iOS assets.

this time, other than generating _mostly_ smaller `png` files (some splashes were actually bigger), I found no difference.. the aforementioned output files were still not regenerated.

I can fully understand the `xml` files not being updated in cases where the input assets are `png`, but I would have still expected the `drawable/splash.png` to be regenerated here.. unless this is an old file? in which case, it should be removed from the Ionic templates.

so the crux of my problem then: how can the "Android drawable" `xml` file be generated from these input assets? could this be created programmatically from the SVG source assets?

> **on a related note**... I did have _some_ difficulty generating the `AppIcon` iOS images for `20x20`, `29x29` and `40x40`, including all `@1x`, `@2x`, `@2x-1` and `@3x` variations, **until** I added the following two additional asset files:

> * `logo-dark.png`
