# Functions
DwarfEndian determines the endianness of the DWARF by using the version number field in the debug_info section Trick borrowed from "debug/dwarf".New().
Parse takes in data (a byte slice) and returns FrameDescriptionEntries, which is a slice of FrameDescriptionEntry.

Value is rule.Reg + rule.Offset.
Value is stored at address rule.Reg + rule.Offset, but only if it's less than the current CFA, otherwise same value.
