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.
stream-name is called ndi-name everywhere in the NDI SDK and documentation
ip is called ip-address everywhere
Rename loss-threshold to timeout and change it to be in milliseconds
instead of iterations.
Add connect-timeout for timeout during connection
Add bandwidth and receiver-ndi-name properties, and initialize the
latter with a reasonable default value.
