f890abe5cb Add support for receiving compressed data from the source 
This requires building against and using the NDI Advanced SDK and is
opt-in via the "advanced-sdk" cargo feature.

8cf682d72b Move to NDIlib_recv_capture_v3() and NDIlib_send_send_audio_v3() 
These allow more control over the data that is being sent/received, but
require NDI SDK 4.0 or newer.

9a53bcd405 Implement remote/local clock estimation with the same algorithm as the RTP jitterbuffer 
This gives fewer jumps and generally leads to smoother and more correct
results, while at the same time also being faster.

This directly uses the receive times of each packet.

2345c455c1 Add initial version of NDI sink 
The sink can accept audio or video directly, or if both should be
provided at once it is necesary to use the ndisinkcombiner before the
ndisink to merge both audio and video into the same stream.

84e4fe7f59 Add new timestamp mode based on the receive time and timecode 
In addition to the old one based on the receive time and timestamp.

Also make that new mode the default as it will usually give more
accurate results because the timestamp is just the send time while the
timecode is usually set by the sender based on the media timestamps.

4d620cd737 Allow connecting to either an NDI name or URL/address again 
Apparently the SDK allows both but the documentation was a bit
confusing.

8d2c025e47 Allow creating source elements from the device provider and don't do discovery during element setup anymore 
While making it possible to create elements from the device provider,
this also speeds up the connection generally when starting up the
elements.

Also add the url-address property for additional filtering in addition
to the NDI name.

afc301de3a Port to NDI SDK v4 
Most notably this allows the video line stride to be set to 0, in which
case a default value is to be used, and it deprecates selecting NDI
sources by their IP address and because of that we remove the relevant
properties.

Usually the SDK will give an URL instead of an IP address now, so usage
would've been broken anyway.

7246b1b147 Don't do anything in BaseSrc::negotiate() 
We can't negotiate anything meaningful with downstream and will always
set the caps based on the data we receive in ::create() later.

5e5007091e Always return 1 frame of latency except for timecode mode 
This allows for some slack when receiving, as up to 1 frame difference between
receive times can easily happen because of capturing alone.

And return 5 frames maximum latency as that is the size of our internal
queue.

33370e42ad Collect observations for the timestamp/receive time mappings and smoothen them 
This allows keeping audio/video more in sync with how the sender was
sending it, while also handling network jitter and clock drift in a
reasonable way.

66d4fd1d90 Move connecting and capturing to separate threads 
This ensures that we'll be able to capture every frame even if
downstream of the source is blocking for a moment, and also allows us to
make all operations cancellable.
