Research direction

Start by reviewing dependency #133 and the requested iOS kernelcache and Android zImage formats. The issue names no files or tests, so first identify the project's loading entry point and establish how native decompression should support both formats without external img4 or gzip tooling. Done means those kernel binaries load natively.

Written by the indexing model from the issue text.

Description

Component: BinaryViewType Impact: Medium

What is the feature you'd like to have?
Native support for decompressing the kernel binaries of major mobile platforms so they can load natively without external tooling/processing. IDA natively does this for kernelcaches, and it's a very handy usability fix. (zImage and iOS kernelcache are the main ones I care about).

Probably dependant on #133

Are any alternative solutions acceptable?
I mean, you can use open source img4 tooling and gzip command line tooling, but it would be nice if Binja could handle this natively.
