v3.15.3

=== Fixes ===
* The JSON reporter's number handling is locale-independent. (#3176)
* Removed leftover debug message from `catch_discover_tests` (#3177)
* Fixed typo in the "Could not jump to the Nth element" exception message (#3181)

=== Improvements ===
* `catch_discover_tests` registers tests in deterministic (alphabetical) order.
* `catch_discover_tests` has been rewritten to be massively faster.
  * Preparing the actual CTest script is significantly faster.
  * Parsing the JSON test array is significantly faster.
  * Running without `ADD_TAGS_AS_LABELS` set is 10-15% faster (as opposed to being the same speed) (#3169)
  * The new implementation is about 4x-5x faster, so registering 500 tests now takes ~350ms (down from 1.1s).
* JSON writing is faster
  * Small improvement in writing non-string values
  * ~6-40% improvement in writing string values that do not need escaping
  * ~1-6% improvement in writing string values that do need escaping
* Better support for infs and NaNs in JSON output
