This allows real-time threads to join an audio workgroup on Apple platforms.

Status codes are already filtered in curlHeaderCallback, so there's no
need to remove them again in parseHttpHeaders. Request headers will
never include a status, so there's no need to remove the status in that
case.

- macOS behaviour of setRealtime now matches other platforms

MR feedback

- added unit tests
- best performance timers used for each platform
- fixed an issue in which timer callbacks could drift

This commit adds fixes for generating unique hardware IDs on Windows. The SMBIOS is parsed to generate a unique ID based on hardware factors of the local machine.

This commit adds the JUCE_DECLARE_SCOPED_ENUM_BITWISE_OPERATORS macro, enabling bitwise operators on scoped enums. This feature simplifies the use of scoped enums in situations where bitwise operations are needed.

Android devices won't necessarily be able to load MP3 files, so that
option has been removed from the file chooser. FLAC files should be
supported, but were missing from the MIME table.

The demo no longer tries to load files into the thumbnail view if they
previously failed to load into the transport.

This allows paths that are prefixed with environment variables to behave
as expected. This is useful when scanning the default LV2 locations in
the AudioPluginHost on Windows.
