Optionally do not draw the outline of the object on a transparent background

[Dmitro25]

Hello! Thanks for the useful application.
Could you add an option to not draw the outline of an object on a transparent background? The presence of the gray contour is clearly visible in the following picture:

on the left is the result obtained by your application; on the right is the frame of the same animation being played in the browser. The background of the animation is transparent.

This is actually a bug, as outline is not present in source lottie animations so it shouldn't be an optional parameter. Thanks for pointing this out

@Dmitro25 please switch on v1.0.1

Thank you, it works. The outlines are gone.

I would also recommend making the default output path (the "-o" option) not "", but ".", otherwise under Windows without this option the results are saved to an unknown location, otherwise they will be saved to the current folder.
