print stack traces for panics

[ghost]

As with other errors, only print the stack trace if --internalDebug.

This resolves #270. Note that it only affects console output, not analytics tracking.

To test, I added a nil deref in js/express.go:

func (p ExpressHandler) Transform(result *core.CompilationResult, deps *core.Dependencies) error {
	var err error
	_ = err.Error()
	...

Default:

$ klotho . -paws --app ys
Adding resource exec_unit:main
[err 0] runtime error: invalid memory address or nil pointer dereference
Klotho compilation failed

With --internalDebug:

$ klotho . -paws --app ys --internalDebug
Adding resource exec_unit:main
[err 0] runtime error: invalid memory address or nil pointer dereference
