v0.12.0-p0

Tensor shapes and positions now explicitly track the tensor's rank.

breaking changes:

• fdeep::tensor5 has been renamed to fdeep::tensor
• fdeep::tensor5_pos has been renamed to fdeep::tensor_pos
• fdeep::shape5 has been renamed to fdeep::tensor_shape
• dropped support for shape inference in reshape layers

deprecated functions (will likely be removed from the API soon)

• float_type fdeep::tensor5::get(std::size_t, std::size_t, std::size_t, std::size_t, std::size_t) const: Please use float_type fdeep::tensor5::get(const tensor_pos&) const or float_type fdeep::tensor5::get_ignore_rank(const tensor_pos&) const instead.
• void fdeep::tensor5::set(std::size_t, std::size_t, std::size_t, std::size_t, std::size_t, float_type): Please use float_type fdeep::tensor5::set(const tensor_pos, float_type) or float_type fdeep::tensor5::set_ignore_rank(const tensor_pos&, float_type) instead.
