Remove --compile-tsp functionality.

[tjprescott]

Closes #72.

This breaking change removes all complexity associated with running the tool with --tsp-compile. It will now require you point --lhs and --rhs at two Swagger specs. This is done with the goal of keeping the core logic tight. Adding TypeSpec compilation functionality added a lot of unnecessary complexity.

• Since TypeSpec functionality has been removed, please update or remove the FIXME comment to avoid confusion about the purpose of the rootPath parameter.

rootPath: string | undefined, // FIXME: This parameter was likely used for TypeSpec
