Improved V850 Support

This release comes with several improvements for the V850 (in concret e2) cpu. The default disassembler is not really supporting many of the instructions of this architecture, but you can use r2ghidra as disassembler and analyzer which comes with a bunch of improvements for this architecture. Here's a list of the most relevant changes:

• Add support for cyclic memory layouts, this memory model is only supported in some rare architectures like s390, VAX, old ARMs and some V850. And this is not supported by any other static analysis tool (only by some closed source emulators from what @trufae could find).
• Implemented jump table analysis and pointer table size prediction, requires latest r2ghidra to work
• Add /cu command to find UDS dispatch tables and pointers for CAN BUS handling firmwares
• The new omd command makes creating memory layouts for embedded firmwares much easier, but at the end it's just a simplified version of om.
• Add slurp:// uri handler which does the same as oom to reload the given disk file into a malloc:// which is ideal for loading firmware dumps with ram contents for proper emulation.
• Fix PSW register bits definition for v850
• Added default calling convention for v850e2-gcc

ARM64/Apple support

• Android binary XML decoder available in the new pFa command (thanks @meme)
• Added support for the new CoreSymbolication file format (thanks @mrmacete )
• Support the latest dyldcaches from macOS/arm64 (thanks @meme)
• Add core plugin using @Siguza 's arm64xref search code which is 200x faster than /r with capstone
• Fixed large loading times and segfaults when loading some corrupted mach0 binaries
• Improved ARM32 LDR esil emulation which may fix some missing xrefs

Analysis

• New command: aaw, flag all words pointing to known flags
• Float/Double/LongDouble types supported in pf [fFG] and wv[fFG]
• Better handling errors when parsing invalid register profiles
• Add =RS directive to define the default register size.
• Assign pdc, pdd, pdg, pdz to their respective decompilers
• Honor all asm.cpu values for the powerpc GNU disassembler
• Added levenstein binary diffing path APIs
• Improve pdc pseudo-decompiler output (show orphaned bbs) + pdcj support
• Add support for new crypto keys on CPS2

Search

• Add brand new implementation of ssdeep (by @trufae) under the MIT license.
• Fix /ad command results are now correct and tested.
• New sixref command (see siguza's plugin in the arm64 section)

Shell

• Add lsr, whoami and uid commands
• Move the Vlang rlang plugin from -extras to core. it's now stable and ready to use.
• Add scr.loopnl to add a newline on all the @@ loops
• Improved dmi commands to load more symbols in debugger mode

• Fixed segfaults and large loading times on 6502, PYC, DEX, MACHO, ELF, DWARF formats
