Update for KDFCounterGenerator to beter implement NIST SP800-108's alternate inputData orderings

This branch updates the KDF Counter Generator and related files to better support the alternative modes as described in NIST SP800-108.

This mode was added as it is used often in Javacard smartcards, notably the newest smartcards which support Global Platform Card Specification 2.2 with Amendment D, for Secure Channel Protocol 03.

NIST SP800-108 allows for alternative orderings of the input fields, meaning that the input can be formatted in multiple ways.
There are 3 supported formats:  - Below *[i]_2* is a counter of *r*-bits length concatenated to the fixedInputData.
1: K(i) := PRF( KI, [i]_2 || Label || 0x00 || Context || [L]_2 ) with the counter at the very beginning of the fixedInputData (The default implementation has this format)
2: K(i) := PRF( KI, Label || 0x00 || Context || [L]_2 || [i]_2 ) with the counter at the very end of the fixedInputData
3a: K(i) := PRF( KI, Label || 0x00 || [i]_2 || Context || [L]_2 ) OR:
3b: K(i) := PRF( KI, Label || 0x00 || [i]_2 || [L]_2 || Context ) OR:
3c: K(i) := PRF( KI, Label || [i]_2 || 0x00 || Context || [L]_2 ) etc... with the counter somewhere in the 'middle' of the fixedInputData.

This function must be called with the following KDFCounterParameters():
 - KI
 - The part of the fixedInputData that comes BEFORE the counter OR *null*
 - the part of the fixedInputData that comes AFTER the counter OR *null*
 - the length of the counter in bits (not bytes)
 
The resulting function calls: (assuming an 8 bit counter)
1. KDFCounterParameters(ki, *null*, "Label || 0x00 || Context || [L]_2]", 8);
2. KDFCounterParameters(ki, "Label || 0x00 || Context || [L]_2]", *null*, 8);
3a. KDFCounterParameters(ki, "Label || 0x00", "Context || [L]_2]", 8);
3b. KDFCounterParameters(ki, "Label || 0x00", "[L]_2] || Context", 8);
3c. KDFCounterParameters(ki, "Label", "0x00 || Context || [L]_2]", 8);


This branch updates:
**KDFCounterBytesGenerator.java**: with the actual modifications in the algorithm.
**KDFCounterParameters.java**: with the modifications to the input, splitting it into two subsets.
**KDFCounterTests.java**: with the required changes to automatically test the KDF functions.
**KDFCTR_gen.rsp**: contains an updated version of the NIST testing and validation vectors required to test the modifications thoroughly.
