Add device `onTransfer` callback, invoked at the start of each request
Example use case is for ILI9341 display which has an additional CMD/DATA control line.
Callbacks should be in `startRequest()` not `nextTransaction()`
Add fast re-queuing support
Where available, next packet is queued **before** invoking completion callback.
Completion callback can return false to re-queue request immediately.
Replace `Request::prepare` with `Device::wait` method
Update Host controller
Useful for debugging upper layers
Use thread for host SPI, add stats
Add `HSPI_ENABLE_STATS` build variable
Add checks to ensure both Controller and Device are initialised
Check for aligned reads, avoids overwriting end of misaligned buffers
Add `MemCheckState` class (moved from TFT_S1D13781 library)

@mikee47 Look at the failing CI tests. Some compilers require small code changes. |

An asynchronous graphics management library intended for SPI-based displays.
On first use several required python modules must be installed. Try building a sample application:
```
cd $SMING_HOME
make fetch Graphics
cd Libraries/Graphics/samples/Basic_Graphics
make python-requirements
make
```
Currently only the ILI9341 display has a driver, but you can use the virtual screen for testing.
This is a display device for use by the Host Emulator. The 'display' is a python application which communicates
with the Sming :cpp:class:`Graphics::Display::Virtual` display driver using a TCP socket.
Graphics processing is handled using SDL2.
To start the virtual screen server type ``make virtual-screen`` from your project directory.
The default TCP port is 7780. If you need to change this, use::
make virtual-screen VSPORT=7780
The screen server's IP address is shown in the caption bar.
Build and run your project in host mode as follows::
make SMING_ARCH=Host
make run VSADDR=192.1.2.3
