README.md: add disclaimer for this fork
actorlib/structuring: add reverse parameter to Unpack and Pack
flow/actor: add packetized parameter for Sink and Source
flow/actor: add __getattr__ on _Endpoint to be able to access directly payload elements
fhdl/verilog: apply patch from David Carne to prevent simulation hanging
The generated code is less clean but is at least usable on simulation
without the need to adapt the coding style to this issue. This has to
be cleaned up to be merged, but this is really an essential feature.
