Changes the formats dropdown for decklink output to only show formats
using the same framerate as OBS does. OBS cannot perform framerate
conversions, meaning that if OBS's framerate is set to 45fps, and
decklink output is set to 60fps, the output will either lag heavily
or simply not function.
The actual crash is caused because obs_module_unload() is called before
the decklink outputs are stopped. In obs_module_unload(), the deviceEnum
pointer is freed. During decklink_output_stop(), the removed code tries
to retrieve a reference of the decklink device from the deviceEnum and
crashes because it has already been freed. This code appears to serve no
purpose anyway, so we remove it.
As os_gettime_ns() gets large the current scaling methods, mostly by casting
to uint64_t, may lead to numerical overflows. Sweep the code and use
util_mul_div64() where applicable.

Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
