Improve samples

[domn1995]

As a developer who is considering using Dunet, I want a collection of different real-world samples to help me determine if the library makes sense for my use case.

As a current user of Dunet, I want a collection of different real-world samples to help me better understand how/when to use the library.

Sample ideas:

• Web application: A result union that models the outcome of some business logic. This result is passed back to a controller to be mapped into the proper response.
• Improved calculator: Model an operation as a union of operators. Calculator logic depends on the user selected operator.
• Web Client: Monads to represent different HTTP request results. Option monad for operations that may return nothing. Result monad for an operation that can succeed with a result object or fail with an error object.
• Implicit conversion sample.
• A blazor sample would be nice too. Was asked about it on twitter: https://twitter.com/shunjiey/status/1541488240225439744?s=20&t=nCBOdq3MBeNGu6kwE4TV3w
