fast-equals: TypeScript errors with v4

The latest version results in a bunch of errors when TypeScript is configured with the following settings:

tsconfig.json

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "forceConsistentCasingInFileNames": true,
    "strict": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "noImplicitOverride": true,
    "noPropertyAccessFromIndexSignature": true,
    "noImplicitReturns": true,
    "noFallthroughCasesInSwitch": true,
    "sourceMap": true,
    "declaration": false,
    "downlevelIteration": true,
    "experimentalDecorators": true,
    "moduleResolution": "node",

    "target": "es2020",
    "module": "es2020",
    "lib": ["es2020", "dom"],
    "types": ["node"]
  }
}

Errors when trying to compile:

I already tried adding "skipLibCheck": true to compilerOptions but it did not fix it.

Downgrading to version v3.0.3 fixes this issue.
