fix(es/minifier): Fix analysis of parameters (#5954) 
**Description:**

Although the author of the issue talked about `@react-pdf/renderer`, it's a bug related to `brotli`, not react pdf renderer.

After investigation, I found that the bug is caused by not marking parameters as initialized. So I fixed the analyzer.

Minifier

EcmaScript minifier for the SWC project. This is basically a port of terser.

Note

Currently name mangler is very simple. To focus on creating a MVP, I (kdy1) will use simple logic for name mangler and implement the content-aware name mangler after publishing first non-beta version.

Debugging tips

If the output contains variables named e, t, n it typically means the original library is published in a minified form and the input contains eval. The current swc name mangler does not do anything if eval is used.

Profiling the minifier

From mac os x, run

./scripts/instrument/all.sh path/to/input/dir
