It is Herwin's resend fix. Test sources are present but not
enabled during library build (will have to implement test build asap).

Made ipaaca-java compatible with ipaaca-python's JSON datatypes. No JSON support on the Java-side though.

fixed overlapping InputBuffer constructors and added BufferConfiguration and BufferConfigurationBuilder

Added BufferConfigurationBuilder to Cpp implementation. Added Channel getter to IUInterface in Cpp implementation. Old constructor interfaces are unchanged to pre-channel versions in Cpp implementation. Added new constructor with BufferConfiguration-parameter for channel usage.

Conflicts:
	ipaacalib/cpp/include/ipaaca/ipaaca.h
	ipaacalib/cpp/src/ipaaca.cc
	ipaacalib/java/src/ipaaca/InputBuffer.java
	ipaacalib/python/src/ipaaca/__init__.py

Added ipaaca channel possibilities based on rsb scope. Also, deprecated incompatible InputBuffer constrcutors for non-container parameters for multiple categories, from cpp version
