added support for launch images for android

[RishabhTayal]

fixes: #53

Probably fixes #49 too

@RishabhTayal Couple of thoughts here:

1. There's no README update
2. From the code it doesn't look like it supports both portrait and landscape images
3. "launch_image" seems too similar to "launcher" - Why not use "splash" instead?

[josh-m-sharpe]

Forcibly resizing the image is probably not a good idea either since the final sizes are all different ratios. You probably want to resize the image to a square and then trim in the sides - that would at least keep the aspect ratio of the original image correct.

Yea - if you remove the ! here: https://github.com/KrauseFx/fastlane-plugin-appicon/pull/54/files#diff-d29e0527a6452a0d57b299118a56018fR64 then aspect ratio is preserved. I suspect most users would prefer it that way.

Any news on this?

Closed due to #54
