Packet size changes

[AndrewCapon]

Hi Guys,

I don't expect this PR to be merged, just as a start to some conversation.

It is related to: #31

To enable new code define ARC_USB_FULL_SIZE=1

For midi devices tested with:

#include <Arduino_USBHostMbed5.h>
#include "USBHostMIDI/USBHostMIDI.h"

mbed::FileHandle *mbed::mbed_override_console(int fd) 
{
  return Serial2;
}

USBHostMIDI hostMidi;

void setup()
{
  Serial2.begin(115200);

  SetupLogic();

  pinMode(PA_15, OUTPUT); //enable the USB-A port
  digitalWrite(PA_15, HIGH);


  printf("Starting USB Midi example...\n");

  while(!hostMidi.connect())
  {
    printf("Waiting for connection...\n");
    delay(1000);
  }
}

void loop()
{
  delay(1000);
}

I also tested the MSD example code and that still works in my testing with two sticks.

Cheers

Andy
