* Adding compile time json path * using string_view * Adding support for compile-time json pointer as well. * Removing unnecessary comment * Tests now working, still will re-review. * Adding documentation on the compile-time json path/pointer parsing feature. * Adding benchmark showing the significant performance advantage of using compiled paths whenever you have them a priori. * going for JSONPath (correct wording). * minor update (mostly doc) --------- Co-authored-by: Daniel Lemire <daniel@lemire.me>
