Add iDump to iOS Tools

[Fi5t]

I'd like to propose adding iDump to the Alternatives section of MASTG-TOOL-0050 (frida-ios-dump).

frida-ios-dump appears to be unmaintained and is currently broken with Frida 17+. iDump was built as a modern replacement — it uses the same core technique but ships as a single Go binary with no Python or SSH setup required, and supports Frida 17+.
