Light library CLI as extras

[jules-ch]

Thank you for developping this neat lib to bind XML to Data object. :)
When running this lib, I need CLI dependencies only for dev but not when running my webservice :

Code generation / CLI :

• click
• jinja2
• docformatter
• toposort

WSDL/SOAP:

• requests

Maybe we can consider adding this as extras to have a light library for parsing & serializing. (only lxml as dependency)

Sounds great!

Thank you for the suggestion @jules-ch

Three extra requirements were added to make the cli, wsdl client and lxml for binding optional.

pip install git+https://github.com/tefra/xsdata@master#egg=xsdata[cli,lxml,soap]
