Support zstd in Wasm by disabling default features

Browse source 
Use case: creating zstd zips in Wasm

Currently it is not possible to create zstd zips in Wasm due to the default
`zdict_builder` needing additional code that will cause compilation to fail for
wasm32-unknown-unknown: https://github.com/gyscos/zstd-rs/issues/210

Since the zip crate's zstd implementation does not use anything from the
`zdict_builder` feature, I've disabled it.

I've gone a step further and disabled the other features as well (`arrays` and
`legacy`), as they are either unused (`arrays`) or a legacy format from 7 years
ago that predates when the zip format supported zstd.

So far this patch has been working well for the Wasm application, and figured I
should upstream it.
