DMR: Fix Hytera PDU Decryption to operate at Block Level; (Fixes confirmed data); #372
DMR: Hytera Enhanced RC4 allows variable len output for OTA, PDU or Voice;
DMR: Fix Segfault in RS12,9 encoder function where freeing static memory caused a crash;
Misc Code tweaks to accomodate new features;
RAS Implementation includes converting RAS 6-24 character passwords into 56-bit RAS Effective Key Values and Performing RAS Permutations on RAS Enabled Burst Types to Calculate the Correct MAC attachment to validate messages;
Better Handling for RAS indicators found in BPTC 196,96 Reserved Bits and handling for RAS indicator bits found in embedded link control opcode byte;
Users may either enter the RAS password with the -$ option, or the 56-bit effective key value with the -y option.
Users will no longer need to use the -F option to bypass CRC errors on RAS enabled payloads when FEC does not explicitely fail.
Removed the old float audio -y option.
