Shrinking to minimal Ghostscript WASM lib

[fdimarh]

I built Ghostscript as a WASM library, but the output is around 54 MB, like ochachacha/ps-wasm. Could you share a step-by-step guide or tips to shrink the build as much as possible (similar to what you did)? Thanks!

I genuinely do not recall how I reduced it (or even if I actively did something because it used to be inside the ochacha project: ochachacha/ps-wasm@8f99d59)

What I can offer you is the next generation that @jkrimmer did: https://github.com/jkrimmer/ghostpdl-wasm/ -> the end result is about 20.4MB.
I still need to merge the new generation in mine (PR #7)
