Feature request: API for character creator

[jonepatr]

Would be great to be able to post a request with the input parameters and receive a json reply with a character!
Would also be nice if CORS was handled so that one can do it from javascript without XSS issues in the browser.

[Grauenwolf]

The RA project has a CORS example that's already been tested.

Cap the number of characters generated at something reasonable and send them as an array.

Add a Help page with a link to the Swagger page.

What are the rules for mixing Blazor and WebAPI? Probably just something in the startup order.
