Typescript type errors

Hi there,
I'm running into loads of type errors from linkedom when using the library in a typescript project.

These type errors appear to all be either missing properties or incorrect implementations of base class methods (due to parameter types or return types not matching).

The errors are too long to send but I will send a few:

node_modules/linkedom/types/dom/parser.d.ts:12:5 - error TS2416: Property 'parseFromString' in type 'DOMParser' is not assignable to the same property in base type 'DOMParser'.
  Type '<MIME extends "image/svg+xml" | "text/html" | "text/xml">(markupLanguage: string, mimeType: MIME) => { "text/html": HTMLDocument; "image/svg+xml": SVGDocument; "text/xml": XMLDocument; }[MIME]' is not assignable to type '(string: string, type: DOMParserSupportedType) => Document'.
    Type 'HTMLDocument | SVGDocument | XMLDocument' is not assignable to type 'Document'.
      Type 'HTMLDocument' is missing the following properties from type 'Document': URL, alinkColor, anchors, applets, and 181 more.

12     parseFromString<MIME extends keyof {
       ~~~~~~~~~~~~~~~

node_modules/linkedom/types/html/anchor-element.d.ts:4:14 - error TS2420: Class 'import("C:/Users/felis/home/projects/test-linkedom/node_modules/linkedom/types/html/anchor-element").HTMLAnchorElement' incorrectly implements interface 'HTMLAnchorElement'.
  Type 'HTMLAnchorElement' is missing the following properties from type 'HTMLAnchorElement': charset, coords, hreflang, name, and 132 more.

               ~~~~~~~~~~~~~~~~~

node_modules/linkedom/types/html/document.d.ts:6:9 - error TS2416: Property 'all' in type 'HTMLDocument' is not assignable to the same property in base type 'HTMLDocument'.
  Property 'namedItem' is missing in type 'NodeList' but required in type 'HTMLAllCollection'.

             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    'namedItem' is declared here.

node_modules/linkedom/types/html/document.d.ts:15:9 - error TS2416: Property 'title' in type 'HTMLDocument' is not assignable to the same property in base type 'HTMLDocument'.
  Type 'HTMLTitleElement' is not assignable to type 'string'.

15     set title(arg: HTMLTitleElement);
           ~~~~~

Workaround: tsc --skipLibCheck

It'd be great to get the types correct here so --skipLibCheck isn't needed. I would make a PR for this however it seems design decisions would need to be made to fix the types. I'm not sure if the types can be reconciled while still extending / implementing globalThis.DOMParser, globalThis.HTMLElement, /globalThis\.HTML.*Element/, etc.

Reproduce the errors with TypeScript and inspect the declarations under types/dom/parser.d.ts, types/html/anchor-element.d.ts, and types/html/document.d.ts alongside TypeScript's lib.dom.d.ts. Compare the reported inherited and implemented signatures to determine whether the types can be reconciled with the global DOM interfaces. Done means the reported type errors no longer require tsc --skipLibCheck.
