Vimeo API 3.4 removed link_secure #201
Description
Although it is not explicitly mentioned in the changelog (https://developer.vimeo.com/api/changelog#3.4), Vimeo API 3.4 seems to have removed the link_secure field.
Whith Accept: application/vnd.vimeo.video+json;version=3.2 the field is present in the response, with Accept: application/vnd.vimeo.video+json;version=3.4 it is not.
I don't think it is a bug in the API, because it is also not listed in the current API docs (https://developer.vimeo.com/api/reference/response/video-file).
This unfortunately results in a bug with in this library since now the ***SecureLink properties are always null.
As far as I can see, the vales of link and link_secure are always the same with the 3.2 API anyway. So ***SecureLink properties maybe could just be removed. (But I am not an expert on the Vimeo API so maybe there is a difference I am not aware of.)
Since this would be a breaking change, a temporary fix could also be to deprecate the properties, return the values of the regular Links and remove the properties in the next major update.
