Server crashes when HTTP version number is large

Description: the server crashes when you type a very large HTTP-version number.

Error message: "terminate called after throwing an instance of 'std::out_of_range' what(): stof"

How to reproduce run web-server as instructed in the project's readme. While server is running, use telnet localhost 8080 to send a GET-request. In order to make the server crash, type "GET "urlstring" /HTTP.
