Support for ELF files - Go string extraction

Lower priority

Would be neat though if the patterns still work and we could leverage elffile or similar.

A Question, What is the difference between this issue and Issue #785?
I have added the ELF magic number in SUPPORTED_FILE_MAGIC and it just prints static strings from go binary. (Still need to add file format identifier logic in go string extraction)
Floss only works on GO and Rust PE binaries right? So to support it on ELF binaries we will have to add string extraction logic for go elf and rust binaries as well correct?

+1. The floss README doesn't mention that this and other features are specific to PE binaries, so I was surprised that I couldn't use this feature for Go ELF binaries. I'd love to be able to.

Thanks for providing such an innovative tool for researchers!
