Suggestion: make Brotli quality level configurable

[OliverJAsh]

Problem

At the moment the Brotli size is calculated using max quality (11).

build-tracker/src/api-client/src/modules/readfile.ts

Line 34 in 371e54e

output.brotli = brotliSize.sync(contents);

https://github.com/erwinmombay/brotli-size/blob/6247b27b4c9c635cce5a6a781248fa0196208426/src/index.ts#L19

However, we are using quality 4 (for various reasons).

We would like the Brotli size in Build Tracker to match the size of our compressed assets in production.

Proposed solution

A setting to control the quality level that would be passed through to brotli-size.
