Bumps terser from 5.1.0 to 5.4.0.

Changelog

v5.4.0

Logical assignment

Change let x = undefined to just let x

Removed some optimizations for template strings, placing them behind unsafe options. Reason: adding strings is not equivalent to template strings, due to valueOf differences.

The AST_Token class was slimmed down in order to use less memory.

v5.3.8

Restore node 13 support

v5.3.7

Hotfix release, fixes package.json "engines" syntax

v5.3.6

Fixed parentheses when outputting ?? mixed with || and &&

Improved hygiene of the symbol generator

v5.3.5

Avoid moving named functions into default exports.

Enabled transform() for chain expressions. This allows AST transformers to reach inside chain expressions.

v5.3.4

Fixed a crash when hoisting (with hoist_vars) a destructuring variable declaration

v5.3.3

source-map library has been updated, bringing memory usage and CPU time improvements when reading input source maps (the SourceMapConsumer is now WASM based).

The wrap_func_args option now also wraps arrow functions, as opposed to only function expressions.

v5.3.2

Prevented spread operations from being expanded when the expanded array/object contains getters, setters, or array holes.

Fixed very slow self-recursion in some cases of removing extraneous parentheses from + operations.

v5.3.1

An issue with destructuring declarations when pure_getters is enabled has been fixed

Fixed a crash when chain expressions need to be shallowly compared

Made inlining functions more conservative to make sure a function that contains a reference to itself isn't moved into a place that can create multiple instances of itself.

v5.3.0

Fixed a crash when compressing object spreads in some cases

Fixed compiletime evaluation of optional chains (caused typeof a?.b to always return "object")

domprops has been updated to contain every single possible prop
