Video without extensions won't work about ngx-gallery HOT 1 OPEN

So I made some changes in a fork and have made a pull request. I checked that all the tests passed and added some new tests for the changes I've made.

Basically this change will let you specify the type of the 'image'. By using the image.type you can specify whether it's an image or a video. The type will be used first if specified, but the function will fall bcak to a slightly altered version of the existing functionality if the type is not specified, where it will attempt to derive the file type from the extension.

Currently the function just splits the filename by . and then pops the last element, assuming that it's a file extension. The change will do the same, except remove anything after a special character, so: mySpecialImage.jpg?alt=media&token=SDFDSFSS will return an image.

I'm new to contributing to projects so happy to make any changes required.
