Add an optional limit to downloaded files

[ju-gu]

User Story
The current implementation of download files (which is already really nice to have) always downloads a whole corpus. Though sometimes one wants to download just a smaller sample of the corpus to do experiments with. Therefore it would be nice to have the option to set a maximum amount of files to download.

Behaviour:
CLI:

deepset-cloud download --limit 100

SDK

download(limit=100) 

to download just a subset of files

As a quick fix you could just run deepset-cloud download and cancel the request after a couple of seconds/minutes etc. But thats definitely just a quick fix!

Will add this as a feature request :)
