* [vcpkg metrics] start using json library
Additionally, add floats to the JSON library since they're required.
* [vcpkg metrics] allow users to disable metrics after the build
Additionally, as a drive by, fix UUID generation
* fix metrics data
* code review
* [vcpkg] Add initial JSON support
This adds a JSON parser, as well as the amount of unicode support
required for JSON parsing to work according to the specification. In the
future, I hope to rewrite our existing XML files into JSON.
Additionally, as a drive-by, we've added the following:
* add /wd4800 to pragmas.h -- this is a "performance warning", for when
you implicitly convert pointers or integers to bool, and shouldn't be
an issue for us.
* Switched Parse::ParserBase to read unicode (as utf-8), as opposed to
ASCII
* Building again under VCPKG_DEVELOPMENT_WARNINGS, yay!
