Address the clang-tidy findings of the view's parser
- tables as std::array; the frames of the first 64 levels stay a C array (not initialized on purpose, NOLINT) - \u escapes are decoded with the library's hex_codepoint() instead of a second table - the parse failure is private, with an accessor; the special member functions of the builder are all declared - no nested conditional operators; explicit parentheses; a repeated branch body merged; auto for casts - the test's C arrays, fixed seed, and escaped literals are marked, as in the other tests Signed-off-by: Niels Lohmann <mail@nlohmann.me>
