Feature request: print xsdata version to console and code comment

[bjhend]

It would be nice if xsdata would print its version information to

• the console when it generates code
• as a comment into the main __init__ file or alternatively some readme file

Rationale

I'm currently debugging a problem that might be solved in a newer xsdata version. To compare the generated code, I have different xsdata versions generate code in different Python virtual environments. Printing the version to the console would ensure that the intended xsdata version was called.

To have comparable code I use the same --package argument in all cases. After copying the code to the project it is hard to tell which code was generated with which xsdata version. A comment in __main__ with the version would help to find out.

Thank you for the suggestion @bjhend, I am not a fan of this kind of branding eww, but I see why this would be usefull.

I added it as a config option, default: off,

xsdata generate --include-header schema.xsd

I also added a header message in the cli to print the current xsdata version, python version and platform.
