Needed HID Parser to support Bidirectional Transfers The HidParser code was setup such that the claim for a report, the caller could say I want to claim the whole thinig and allowed callback functions for processing of in buffer and out buffer. Allow RawHID to contribute Transfer_t Since RawHID may need more resources than most, maybe it should contribute the additional structures The constructor for a RAWHID object allows you to specify the top usage that it wishes to connect to. I used this for example to be able to connect to a Teensy with the RAWHID associated with emulating the Serial object. If a HID Input class says that it wants to claim the whole interface, I reuse the buffer associated with holding the HID descriptor and use it for output buffers.
