[dependabot]

Bumps terser from 5.16.0 to 5.16.4.

Changelog

Sourced from terser's changelog.

v5.16.4

• Keep (defaultArg = undefined) => ..., because default args don't count for function length
• Prevent inlining variables into ?. optional chains
• Avoid removing unused arguments while transforming
• Optimize iterating AST node lists
• Make sure catch and finally aren't children of try in the AST
• Use modern unicode property escapes (\p{...}) to parse identifiers when available

v5.16.3

• Ensure function definitions, don't assume the values of variables defined after them.

v5.16.2

• Fix sourcemaps with non-ascii characters (#1318)
• Support string module name and export * as (#1336)
• Do not move let out of for initializers, as it can change scoping
• Fix a corner case that would generate the invalid syntax if (something) let x ("let" in braceless if body)
• Knowledge of more native object properties (#1330)
• Got rid of Travis (#1323)
• Added semi-secret asObject sourcemap option to typescript defs (#1321)

v5.16.1

• Properly handle references in destructurings (const { [reference]: val } = ...)
• Allow parsing of .#privatefield in nested classes
• Do not evaluate operations that return large strings if that would make the output code larger
• Make collapse_vars handle block scope correctly
• Internal improvements: Typos (#1311), more tests, small-scale refactoring
