v1.0.1

First public release of the major update to ptokens.js library.
ptokens.js has been entirely rewritten from scratch (the previous version can be found here.

In particular:

• It is entirely written in Typescript, but there are ready-to-use bundles to integrate it in your backend/frontend application
• It is object-oriented designed and implementing the builder pattern to ease objects creation
• It permits host-to-host swaps, unleashing the pTokens to pTokens bridge feature
