Release 6.0.0

Breaking change

This release introduces the following backwards-incompatible changes to the public API:

• All methods to attach interrupts (e.g., setDioAction(), setGdoAction() etc.) no longer have a default level change direction.
• Signature of all methods/functions that use pin numbers (e.g. the Module constructor) changed from platform-dependent "pin type" changed to a common type (uint32_t)
• Reworked hardware abstraction
