fix: expose parserOptions more
As far as I understand, this does not achieve the intended effect: the introduced ParserOptions from n3 is different from the ParseOptions in the getSolidDataset options (see https://github.com/inrupt/solid-client-js/blob/main/src/resource/solidDataset.ts#L153). This PR adds a new type to the interface, but the passed option will never actually be used, it's just not incompatible with the existing API because it is an additive change.
I think switching to the solid-client ParseOption, and adding that to the API where you were adding ParserOption should get you where you in the right direction.
Thanks @NSeydoux for having a look! I totally didn't see the difference between ParseOptions and ParserOptions, it should be all fixed and correct now
Could you have another look @NSeydoux ?
