The codebase needs only a few additional standard #includes to compile
against libstdc++ on Linux; presumably those headers are implicitly
included with MSVC's and Clang's standard C++ library, but even if
libstdc++ compatibility is not a goal, it is advisable to have them
included directly.
This fixes two different logcat messages that would occur when scrubbing

This adds a WebSockets server to filament-utils-android.
Unlike my first attempt (#3599), this does not use a piping server and
is therefore much faster to use over a LAN. It also has lower user
friction because there is no need to touch a button in the app or
scan a QR code.
