Having a general Endpoint for sending media files

[dhyeythumar]

Currently, according to my understanding, there is only 2 type of endpoint available (image & pdf) to send the media files.
But I think there should be a general endpoint for sending all sorts of media files & that endpoint might take media type as an query parameter or even find the media type on its own.

So I think this should solve any further issues in sending different type files, such as this issue here Send contact card (vcard)

For example: (roughly this both endpoints are doing the same thing)
