Until now, it has been output only in get_format() callback but this
function isn't run by all decoders (eg. when there is no options to
select from).

+ updated the script to work from any UG repo subdir (not only top level)

- install only zfec subdirectory, not whole repo
- macOS blocks creating files directly in /usr(/src)

Although nowadays rarely used, /usr/src is a convenient place for
system-wide sources (aka libraries), so use it. Also it also removes the
need for hard-coded path.

In order not to depend on hard-coded path.

But give it a low priority - the pkg configuration seems to be wrong -
-lCFHDCodecStatic is in LIBS but libCFHDCodec.a is actually generated.

moved modules to separate functions

+ removed gpujpeg/cineform from monitored paths in workflow file

If the environmnet variable NDI_RUNTIME_DIR_V5 is not defined from any
reason, try the location where NDI is usually installed
(C:\Program Files\NDI\NDI 5 Runtime\v5).

+ fixed bold output (was bash specific)

Makes it harder to forget to initialize newly added members

The order of values is minute, hour, day-of-month, month, day-of-week

run only in main repo on schedule

if coverity token is present

The header doesn't yet include the SetThreadDescription() definition but
it is in the UCRT library so ship own declaration of the function for
now.

- pass generated data with testcard_state2::data variable + notify with
  CV to thread that it is available
- use dispose to "automatically" manage grabbed frames

+ fixed leaked text surface

Take it as a dependency

av_frame_wrapper_recycle() and av_frame_wrapper_copy() moved from header
to rpi4_out.cpp.

- do not print device modes + connections - usually not needed because
  there is signal autodetection with recent DeckLink cards and user
  usually knows the connection directly
- print available color space more dense

The outcome is that the output fits (usually) one screen while avoiding
unnecessary items (but print all possible connections).
