Better device proxy cache

[hardillb]

part of #3414

Description

Rather than requesting the 4 largest files from the device agent every time the device editor is loaded it will load them from a local instance on @node-red/editor-client of the matching version if present.

Still need to work out how to install the right versions of @node-red/editor
