Description: Byte packer for AXI-Stream. Accepts an incoming stream and packs data into the outbound stream. Similar to AxiStreamResize, but allows an input and output width to have non multiples and for the input size to be dynamic. This module does not downsize and creates more complex combinatorial logic than in AxiStreamResize.
Ready handshaking is not supported.
