Niels Lohmann 5ac95db5a9 Correct and complete the UBJSON documentation
Fix statements that disagree with the behavior (checked with probes):
- `Z` is null; the unused marker is `N`.
- `$` requires `#`; use_type with use_size=false throws other_error.502 only
  for non-empty arrays, objects and binary values.
- NaN and infinity are written as IEEE 754 float64 and read back unchanged;
  the UBJSON specification encodes infinity as null.
- `H` is documented (semantics, parse_error.115, out_of_range.406); the
  "complete mapping" claim is qualified.
- use_type "same type" means same marker.
- Long Z/T/F arrays lose only the `$` annotation; the `#` count and the
  element markers are kept.
- from_ubjson lists the 112, 113, 115, 406 and 408 causes that occur for
  UBJSON, without the BJData-only ND-array wording.
- Duplicate object keys keep the last value; the `$` type marker is
  validated even for count 0.
- Smaller fixes: float32 row, "map" -> "object", https link, exception 110
  strict case, to_ubjson history of discarded values.
