Customize string representation

[tadfisher]

Kotlin generates a toString method for data/value classes that I'd like to override. There are a couple of particular customizations I'd like to make:

• Redact sensitive info from being potentially logged
• Value classes look like "Type(contents)" when I usually want just the "contents" part

So a nice option to support with #13 could be stringTemplate :: Maybe Text, which would result in a toString() override on the Kotlin backend and perhaps a CustomStringConvertible implementation on the Swift backend.

Can you share (for Kotlin) what the code generated would look like?

Well, after a quick Google search I can see what it would look like. How would we generate the toString implementation? Moat isn't really capable of generating term-level expressions.

Just a string template would work fine, because both Kotlin and Swift do string interpolation. So all Moat would need to generate is

override fun toString(): String = "<stringTemplate>"

and it would be on the user to pass something that makes sense in the context of the type.
