Summary

• This PR adds support for configuring custom fonts in the Rokt Kit initialization.
  It retrieves RoktOptions from the Kit Manager, allowing either fontFilePathMap or fontPostScriptNames to be passed to Rokt.init. These options enable clients to supply custom fonts from assets or pre-loaded Typeface objects when initializing Rokt through the mParticle SDK.
