Add mapTry to Option

[bvkatwijk]

• Add mapTry method to Option, which is a shortcut for .toTry().mapTry
  • I propose this because when mapping an optional using a checked method, I find it intuitive that the type changes to a Try, and mapTry methods exist on other types already
  • I initially added it onto Value but this ran into an issue where a method with same name but return value already exists on subtypeFuture

Unrelated but maybe helpful (I can remove it if desired)

• Add toolchain resolver
  • After forking the project I could not load it in IntelliJ, Gradle complained that it could not resolve the toolchain. Added a resolver as per the Gradle Docs
• Add Nested test class for mapTry tests instead of a comment
  • This achieves organizational separation just like the comment, but now JUnit also understands it and can e.g. run only these tests in isolation.

Thanks for your contribution :) looking good!

Add Nested test class for mapTry tests instead of a comment

makes sense - we've migrated to JUnit5 recently, but we're not leveraging it fully

After forking the project I could not load it in IntelliJ, Gradle complained that it could not resolve the toolchain.

sounds good - could you add it a a separate change, though? so that we don't mix two things together

I initially added it onto Value but this ran into an issue where a method with same name but return value already exists on subtypeFuture

that's something we might want to straighten out before releasing 1.0.0

Proposing to migrate to nested classes in #2951
