Correct README examples for Result and Generic Result of T

[crobinson-expl]

Thanks, @KyleMcMaster for creating this project! It has been nice to work with so far. I noticed that there is mention of a FailWith(...) method in the examples for assertions of Result and Generic Result of T, but these methods do not exist.

@crobinson-expl First, I'd like to say thanks for using the library and opening an issue! I believe the README is actually correct and the functionality appears to be missing from the codebase possibly due to a bad merge or forgetting to PR a branch. I will get the FailWith methods added and release a new version as soon as possible.

Sounds great, thanks @KyleMcMaster!
