Christian Riggenbach 41635e3c68 beginTransactionWithAssertingCS() and endTransactionWithDeassertingCS() 
These two methods are similar to beginTransaction() and endTransaction(),
but, as the name implies, with CS management. They are both public, as
beginTransaction() and endTransaction() are too.

Make compatible with Heltec's CubeCell Arduino-core 
The functions fast pin-I/O uses are currently missing, so don't define BUSIO_USE_FAST_PINIO. Also, we need typedef for BitOrder, but it refuses to compile without also including Arduino.h, at least under PlatformIO.

Fix support for megaTinyCore, add DxCore support 
Testing for the define from build.board is not a good test (I recently updated them to refer to the specific part, instead of just the number of pins, for example) - instead, test for the MEGATINYCORE define, which is defined by Arduino.h and will always be there , and will be for all future versions of megaTinyCore. Also added a test for DxCore, which supports the new AVR Dx-series parts, and does SPI bit order in the same way. I confirmed that the examples now compile again on megaTinyCore with this change - and now compile for DxCore as well

Update Adafruit_SPIDevice.h for Sony Spresense. 
Add support for the Sony Spresense architecture. This has no BitOrder enum, so it's added here.

Daniel Stuart 38ea25d88a SPI: Add Infineon XMC boards to BitOrder quirk 
As many (all?) ARM Cortex based chips, Infineon xmc boards also need
this quirk for BusIO to compile.
