Refactor error expansion to locate errors in koan module
...
The previous strategy wasn't robust enough to detect typos in function
calls. For example, if you misremembered String.duplicate/2 as
String.repeat/2 the koan runner would hang and have to be restarted.
This is because the stacktrace for an error like that doesn't have line
numbers. To avoid the problem, we detect the first pieces of the
stracktrace that is in the koan module. I can't decide if that's a
perfect solution, but it seemed to work in my testing. Hoping to get
other's feedback.

Show left and right hand values when equality fails
...
For assertions that contain function calls, displaying just the
expression is not helpful. For e.g.
Assertion failed
String.upcase("foo") == "Foo"
The learner is given no extra information to help them learn. Sure they
might consult the documentation (and should!), but perhaps a better
experience would be for us to inform the learner about the values it
encountered.
Assertion failed
String.upcase("foo") == "Foo"
left: "FOO"
right: "Foo"
Learner: 💡 ah hah! it upcases the whole string! 💫

Prefer function output over input
...
When learning about the behavior of a function, in general the learning
experience is better when provided with the input and asked for the
output.
