request: support for more platforms

[mcandre]

Hi,

Thank you for publishing this convenient library for quickly compressing and extracting with ZIP archives!

I am using this library to manage archives in a command line application.

Normally, I produce ports of my applications to very many environments. However, I noticed that the implementation is currently restricted to two lanes of the larger OS ecosystem: Windows, and the UNIX family.

It is true that these two cover a lot of Go application environments, however, they don't quite cover Android, iOS/iPadOS, Plan9, or either of the JS or WSAPI flavors of WASM.

Referencing this package from an application ported via factorio triggers Go compilation errors. Would appreciate resolving more of these platforms, so that I can then expand my application to support those niche users as well.
