0.1.0

Release for #43
"New" synchronous capture backend interface, unified for both UI and Video layer capture, where all pixel format conversion, scaling and blending is extracted into a common "unicapture" module.

• backends now expose a simple, unified synchronous interface for a specific layer capture (ie. we now have separate backends for video layers - dile_vt, vtcapture, and ui layers - gm and halgal)
• unicapture module is responsible for backend initialization, frame keeping (vsync) and merging/blending/conversion of different layers.
• converter is responsible for converting frames between colorspaces (via libyuv), intentionally used only in unicapture
• service is a module that binds unicapture module with hyperion_client and exposes Luna bus management service
• settings is a module responsible for converting settings_t structure to/from JSON objects and files (stored in config.json file)
• main only handles initialization and startup of service

Notable changes:

• Added support for UI capture when combined with dile_vt
• Added UI/video backend autodetection (default)
• Added support for automatic pausing of capture when the TV is going to suspend mode (QuickStart+)
• Added "vsync": false option that will help with issues like #30 ("fake" vsync signal will be issued every 1/FPS seconds, instead of using video backend waiting method)
• Unified support for novideo/nogui options in all backends
• Fixed/improved FPS counting/limiting on all platforms
• /status luna service endpoint returns current framerate and info about currently running capture modules
• Disabling autostart will remove the init.d symlink properly now
• General stability improvements
• Code has been reformatted using clangd/clang-format

Known issues:

• TODO: Backend/resolution change requires service restart

Supersedes:

• #47
• #48 - added vsync flag
• #40 - fixed frame pace handling including optional vsync
• #21 - contains support for libgm & libhal_gal UI capture support
