Android - Dynamic initialization of the configuration/pins.

[danielcmihai]

Hello all

Is your feature request related to a problem? Please describe. Dynamically initialise trustkit on android.

Describe the solution you'd like It would be great to be able to initialise trustkit using a TrustKitConfiguration that we craft in the app. If it's not possible would you guys be open to a PR ?

Thank you.
