EMBROIDER_CONCAT_STATS breaks the build

[Windvis]

I'm following the analyze.md guide and when I try the EMBROIDER_CONCAT_STATS=true npm run build command the build fails with the following error:

(0 , filesize_1.filesize) is not a function

Looking at the stack trace and related code, it points to this line:

embroider/packages/core/src/measure-concat.ts

Line 22 in be02b4a

.map(([name, bytes]) => ` ${name}: ${filesize(bytes, {})}`)

Or the compiled version:

            .map(([name, bytes]) => `  ${name}: ${(0, filesize_1.filesize)(bytes, {})}`)

It seems that v5 of the filesize package only has a default export but since it's imported as a named import in the code it fails.

This is the commit that introduced that change: 1d350d9#diff-cfbd9511262fbeca1aa6e2e563f54f6852e46b3ba0db0d1381d693d11fdca2a8L4

The latest version of filesize does support the named import, so I think updating to that should fix this problem. Manually updating the code in node_modules so it uses the default export fixed the issue locally. Forcing it to the latest version with overrides also worked.

I can create a PR but guidance would be appreciated if tests are needed.
