Right now, if we attempt to use cuvid in a media player and then try to seek, the decoder will happily pass out whatever frames were already in flight before the seek. There is both the output queue in our code and some number of frames within the cuvid decoder that need to be accounted for. cuvid doesn't support flush, so our only choice is to do a brute-force re-creation of the decoder, which also implies re-creating the parser, but this is fine. The only subtlty is that there is sanity check code in decoder initialisation that wants to make sure the HWContextFrame hasn't already been initialised. This is a fair check to do at the beginning but not after a flush, so it has to be made conditional.
