Reducing compiled asset size

[bcardarella]

If I compile main the resulting binary is about 15.9MBs. This appears consistent with the size in this repo's Releases.

For various reasons I need to package xcodegen as a local binary but the total size of what I'm building needs to be below 8MBs. I'm wondering if there are ways to bring downt the size of xcodegen?

I used bloaty to check out the compiled binary, unfortunately the recommended -d compileunits flag won't work (missing debug info) but without that flag I get:

Is there anything here that can be stripped out?
