Replace contract hex encoding in SDK

Grant category

Description

As described here https://github.com/onflow/sdks/issues/17 the contract source code needs to be uploaded in raw utf-8 format instead of hex encoding.

Proposed solution

Replace all the hex encoding with source code in string in all related repositories.

These are breaking changes for all the sdk users so therefore everyone needs to be informed about upcoming changes.
