5.0.0-beta.0

This is the first beta version of the 5 major version, which introduces the following changes:

• We drop support for Node 6.x branch.
• Workers are now loaded with inline blobs, which means that is only needed to specify the worker: true option and Paparse will load it's code from a blob
• Step function returns only a single row
• A function to transform header columns is added. The trimheader option is removed as it can be achieved with this new transform function.
• The API throws now Error objects instead of using error Strings.

Please test it and report issues if you have on it. As this is a beta version it should be installed with the following command:

npm install papaparse@beta
