lrdp-v2:minidump parsing support add in ramparser

	A minidump supports fewer features than a full ramdump,
	but does not require the user to save all 4GB+ of memory.
	Instead a small subset of DDR is saved by crashscope as an elf file.
	Currently dmesg logs, rtb logs, and the cpu context parser are supported.

	Example usage: python ramparse.py --vmlinux <vmlinux> --minidump
			--ram-elf <elf_file> --ram-file <OCIMEM.bin> --everything
