Add TypeScript Types

[jamiehaywood]

Adding a TypeScript declaration file would be very useful to consumers to get intellisense on the params and return types.

hi guys, just wanted to follow up to see where you'd got to with the types? currently having to add types to our project like so:

// moneyhub.d.ts
declare module '@mft/moneyhub-api-client' {
  import type { JWK } from 'jose'
  import type { GotBodyOptions, GotJSONOptions, GotFormOptions } from 'got'
  import type { TokenSet } from 'openid-client'

  function Factory(apiClientConfig: APIClientConfig): Promise<MoneyHub>
  export default Factory
  export interface MoneyHub {
    getAuthorizeUrl: (params: {
      state: string
      scope: string
      nonce: string
      claims?: Record<string, unknown>
      permissions: string[]
    }) => Promise<string>

    exchangeCodeForTokens: (params: {
      paramsFromCallback: Record<string, unknown>
      localParams: Record<string, unknown>
    }) => Promise<TokenSet>

// etc...
}

would be great if you could take a look at my PR and merge / rewrite stuff you think is relevant.

Very happy to give some of my time to help with toolchain / build / release process
