Release v1.0.0

Disclaimer: It feels wrong to "release a version" for a repository belonging to someone else, but we need a version tag for the kali upload. Unfortunately the upstream repository is unmaintained for 5 years now with no activity at all, so we will do the "release" 🤷‍♂️

What have i changed from the upstream repository?

• Added RPC constants to properly make use of constants instead of plain integers
• Fixed the RPC authentication which raised exceptions when the authentication was not successful
• Added error handling for different RPC errors so it is possible to track different authentication errors, e.g. "stronger auth required" when kerberos auth is requested by the server
• Added ipv6 support

What was already working in the upstream repository:

• As far as i can tell (and has been tested) the repository fully implements the NFS protocol with version 3 and also provides the portmapper & mounting capabilities
