This is similar to

purescript-gargantext#594

and

!205/

but for JSON import.

Doing so fixes (for now) the Phylo error.

They were masking the real performance of `flowPhyloAPI`.

It's a useful function to log (with `DEBUG` severity) the execution time
of various functions. Debug logs won't be printed in production.

It also improves the error in case it's the first time we are running
the tests and we have no coreNLP service running.

This commit adds a `panicTrace` function to be used as a drop-in
replacement of the `panic` function, with the difference that we
wrap the error in a `WithStacktrace` error, to be later caught
and logged.

This allows us to have only one single (static) map which will be
treated by GHC as a CAF.
