Server crashes on directory traversal attempt with invalid UTF-8 character

Server crashes on directory traversal attempt with invalid UTF-8 character

A scheduled scan kicked off on our network and crashed my npm-lite server. Checking the logs, the crash was on a GET for /%80../%80../%80../%80../%80../%80../windows/win.ini

%80 is not a valid URL encoded character under UTF-8, which may be why it crashed.
### Bug repro steps
1. Launch server
2. Attempt to navigate to /%80../%80../%80../%80../%80../%80../windows/win.ini
3. Server crashes
### Environment
- `lite-server` version: 2.2.0
- `nodejs` version: v4.4.5
- `npm` version: 2.15.5
- OS type/version: Win 7 Enterprise 64-bit
