Implements `PythonExceptionInterpreter` that works as a "catch-all" exception intrepreter for `PythonException`. Since it can interpret more specific python exceptions that are already covered by other interpreters, its `Order` is set to `int.MaxValue` to be the last to be tested.
We format the message before being set to the result handler's log message
method so it ends up being outputted as we wish. The desired output is a
header line with the collated message from the exception (including inners)
followed by the full exception detail (inner stack traces and all).
Often times exceptions are wrapped in other exceptions that are potentially
wrapped in other exceptions (ad. infinum) -- this lends itself to a recursive
strategy for projecting exception instances. This change aims to make exception
projections composable for easy consumption by a recursive algorithm by adding
an innerProjection parameter to IExceptionProject.Project. The individual impl
can decide whether or not it wants to project the inner exception. Additionally,
it can project it using custom logic or using the specified innerProjection, or
it could ignore it completely. The implementations have all the decision making
power.
