CSS class glide__slide missing

[M-Blobby]

When using ngx-glide on my project, I have a flash effect when loading my slides: all slides are visible for a fraction of a second before being displayed correctly. I realized that by adding the glide__slide CSS class directly to my slides this corrected the problem. In reality this comes from the flex-shrink: 0 property, present on this class since the @glidejs package.

Since ngx-glide itself adds the classes glide, glide__track, glide__slides, etc., shouldn't it also add the glide__slide class? Since the slides are injected via an <ng-content />, the solution that seems simplest to me would be to add a directive to the project. Otherwise specify in the README that we must add this class manually to be sure to inherit all the glidejs style.

I would be happy to suggest a PR if my comment is relevant.
