v1.0.0-beta

This is the beta release of the IOTA Go library. All changes are breaking.

Changes:

• Splits functionalities into different packages.
• Removes github.com/tildeleb/hashland/keccakpg in favor of using a modified golang.org/x/crypto/sha3 package for Kerl.
• Makes the API composable so that the underlying transport protocol is abstracted away.
• Adds missing functionality from iota.js, such as: unit, ascii-tryte conversion, guards etc.
• Adds tests for all packages and integration tests for the API object.
• Removes licences from source files and uses a single LICENCE file for reference.
• Rewrites Proof-of-Work implementations to immediately return the nonce when one was found from a given spawned goroutine.
• Decouples concurrent access from the Proof-of-Work implementations, instead, use Sync prefixed functions for handling concurrent access.
• Makes primitive types such as Trits, Trytes and so on alias types, so no explicit type conversion is needed.
• Reduces copying in a lot of for loops by extracting pointers.
• Return errors everywhere in the package where one might occur instead of panicking.
• Marks function which can panic with Must.
• Adds proper CI configuration.
• Renames project to iota.go
