Dear NNStreamer Users and Developers,

Making varying mime-types looks very ugly, I (and @jaeyun-jung, @sangjung-woo, and @anyj0527) have decided to consolidate tensor stream type definitions of GST Capabilities.

1. other/tensor will become deprecated. We will keep backward compatibility for a while; but users are recommended to use other/tensors,num_tensors=1 instead of other/tensor.
2. other/tensors-flexible and other/tensors-sparse won't be created. Instead, we will add format property to the conventional other/tensors.
3. other/tensors's new property "format" has three values for now: { static = default, flexible, sparse }. If not specified, it is static.

We have proceeded with option 3 and most related patches are tested and merged. With a few initial versions of edge-AI related commits merges, we will be marking a new stable version, soon.

This will be tracked at https://github.com/nnstreamer/nnstreamer/pull/3438

When the stream type consolidation is completed with the implementation of "flexible tensors" and "sparse tensors" along with new elements (type converters, tensor-crop/composite, ...) related to new tensor types, we will mark the new stable version, 2.0.0.

Cheers, MyungJoo
