Add yolo support. Yolo model doesn't output final result. It outputs
candidate boxes, so we need post-process to remove overlap boxes to
get final results. Also, the box's coordinators relate to cell and
anchors, so we need these information to calculate boxes as well.

There are many kinds of detection DNN model and they have different
preprocess and postprocess methods. To support more models,
"model_type" option is added to help to choose preprocess and
postprocess function.

Segmented loads are slow, so here we use unit-strided load and narrowing shifts.

Fixes OOM when caller keeps adding frames into filtergraph
that reached EOF by other means, for example EOF is signalled
by other filter in filtergraph or by buffersink.
When using vf_scale to force a specific output color space, also tag
this on the AVFrame. (Mirroring existing logic for output range)
Move the sanity fix for RGB after the new assignment, to avoid leaking
bogus YUV colorspace metadata for RGB spaces.
No need to write a custom string parser when we can just use an integer
option with preset values. The various bits of fallback logic are wholly
redundant with equivalent logic already inside sws_getCoefficients.
Note: I disallowed setting 'out_color_matrix=auto', because this does
not do anything meaningful in the current code (just hard-codes
AVCOL_SPC_BT470BG fallback).
The check if drawing needs to be initialized and supported formats
should be drawable ones was flawed, as pad_stop/pad_start is only
populated from stop_duration/start_duration after these checks.
To fix that, check the _duration variants as well and for better
readability and maintainability break the check out into its own
helper.

We calculated offsets as pairs, but addressed them in the shader
as single float values, while reading them as ivec2s.
Also removes unused code (was provisionally added if cooperative matrices
could be used, but that turned out to be impossible).
