Bumps terser from 5.48.0 to 5.51.2.

Changelog

Sourced from terser's changelog.

v5.51.2

  • Roll back fix for ambiguously scoped default args, due to issues that came up without clear reproduction

v5.51.1

  • Fix transforming code in dynamic import argument.

v5.51.0

  • Pin (deoptimize) functions that use argnames scope in ambiguous way. IE when default args access other args, or variables outside the function.

v5.50.0

  • Experimental TypeScript type stripping
  • Fixed a crash in mozilla AST conversion of imports

v5.49.2

  • Fixed a crash related to dynamic import expressions

v5.49.1

  • Correctly parenthesize tagged template strings where the tag is new something(), which also has parentheses
  • Internally changed how import() expression is parsed, it is no longer treated as a function call.

v5.49.0

  • Add ResizeObserver box option to domprops
  • Do not evaluate exponentiation of BigInt
  • Parse identifiers from newer unicode versions, and escape them for older runtimes
