Bugfixes + 64 bit support + Swift language support

- Fix loading section logic - adding selected architecture offset to section offset
- Verifying existence of DWARF segment
- Arm64 support (tested on many devices)
- DIE subprograms are searched recursively and not single-level only (needed for Swift)
- Added Swift language support - appending parameter names since Swift can have different overloads for same method name.
