== DETAILS
Honor the compression flag and write compressed section data.

== DETAILS
The Wii U uses a slightly customized ELF format which uses
zlib compression on certain section types.

This commit adds the following:
- add `SHT_` constants for the custom ELF sections
- add `SHF_RPX_DEFLATE` flag used to denote a compressed section
- add code in the section `load()` method to detect the `SHF_RPX_DEFLATE` flag
  and decompress the section

Added some types and strings, table for OS/ABI, added OS/ABI and ABI version to dump

It is a duplication of existing Action CI

I just noticed that on my compiler;
probably due to recent version, not sure.

TODO: We might add examples run-time one day.
