## Description 

In this PR: 

- (breaking) Change signature of `purchaseAndResolvePolicies` to a)
support environments (e.g. mainnet, testnet) and b) accept `extraParams`
(_to support kiosk_lock_rule_).
- Support for `kiosk_lock_rule`, enabling the SDK to fully support
`strong royalties enforcement`.
- (breaking) Change return of `purchaseAndResolvePolicies` to include
the item + `canTransfer` flag (whether it can be transferred or not,
based on the ruleset).
- Isolate the Types of the Kiosk SDK and export them all properly (from
`./types` directory).
- Reuse types in bcs definitions.
- Convert functions to plain format (instead of arrow fns) for
consistency.
- Fixes `withdrawFromKiosk` and `withdrawFromPolicy` call amount params.

## Test Plan 

How did you test the new or updated feature?

Right now the changes are tested on the Demo Kiosk dapp that is being
developed in parallel. We'll need to start creating a testing suite for
the SDK, as we start finalizing our requirements.
