Version 0.1 bug fixes and improvements

We've added the parameter sinceModifiedAtto the clientList request, this will filter only clients that have had changes since the date you specify.
You can now create clients using a UK Companies House company number. When creating the client, Firmcheck will also pull the directors and PSCs and include them with that client as related parties. Please see https://developer.firmcheck.com/reference/createclient#/ for more details.
A bug where the clientList was including discarded and archived clients has been fixed, the request now only returns clients that have the state PROSPECT and EXISTING.
