chore(build): update filesize rollup plugin options

[saikumarrs]

Description of the change

Added an option to filesize rollup plugin, which will help compare the size of the output b/w the previous and current build runs. Also, added another option to show the size of Brotli compressed SDK.
This will be helpful during development.

Example output:

analytics.js → dist/rudder-analytics.min.js...
