Returns the set of ids for all exceptions found in the given text (optionally
from the provided set of exception ids), or nil if none were found.

Note: this method has a substantial performance cost. Callers are encouraged
to break their ids into batches and call the 2-arg version with each batch
in parallel (e.g. using `clojure.core/pmap`), then merge the results.

Initialises this namespace upon first call (and does nothing on subsequent
calls), returning nil. Consumers of this namespace are not required to call
this fn, as initialisation will occur implicitly anyway; it is provided to
allow explicit control of the cost of initialisation to callers who need it.

Returns the set of ids for all licenses found in the given text (optionally
from the provided list of license ids), or nil if none were found.

Note: this method has a substantial performance cost. Callers are encouraged
to break their ids into batches and call the 2-arg version with each batch
in parallel (e.g. using `clojure.core/pmap`), then merge the results.
