Release v0.3.2

What's new?

• Token (single) authentication:
  fedn run reducer --secret-key=<your-secret-phrase> will generate a token which will be required for combiners and clients to assign to the network. Clients and combiners are then required to authenticate via fedn run client --token=<generated-token> or by specifying "token" key in settings YAML file.
• Compute package is no longer required to setup via the web UI: fedn run reducer --local-package
  Instead clients will make use of a local compute package, i.e. a remote compute package will not be downloaded.
• VS Code devcontainer has been added

Bugfixes

• Fixes an issue where a client could connect before a seed (initial) model has been uploaded
