[SDK-4039] Make modulereport print gzipped size too

[lawrence-forooghian]

It’s quite likely that some of our users will be serving their bundles with gzip encoding, so this is useful information to have.

Example output

> ably@1.2.48 modulereport
> tsc --noEmit scripts/moduleReport.ts && esr scripts/moduleReport.ts

Resolves #1580.

Just pushed a couple of other commits, to format as a table and add the size of a bundle that includes all modules (a piece of information that @ttypic indicated would be useful to have).
