[New Source Plugin] Static Resource ZIP Compression doesn't seem to be as tight, "static resource cannot exceed 5MB"

[aheber]

Summary

When deploying my static resources I get the error "static resource cannot exceed 5MB" for a single resource where I've dealt with size issues in the past. If I uninstall the new Source plugin then static resources deploy correctly.

Steps To Reproduce:

I don't have a set of files I can share publicly but could share the Static Resource contents private on request.

Expected result

Static Resource should have deployed. The current SFDX (non-Source plugin) packs to a ZIP file that comes in at 4.92MB where the Source-Plugin version packs to 5.13MB.

Actual result

Static resource exceeded the 5MB file size limit and failed to deploy only when using the Source plugin.

@aheber nice catch, thanks for reporting!

I too am hitting this after updating to version 7.112 today; It only seems to happen if I use force:source:deploy to deploy my static resources. I can push the same static resource bundle to scratch orgs using force:source:push with no problem. In my case, the problematic resource is 4,552,560 bytes in my scratch org after force:source:push, but the same static resource bundle cannot be deployed using force:source:deploy because it is exceeding 5 MB.

@mshanemc -- Will this get addressed in this week's CLI release? This is a blocker for CI/CD
