Custom logging

A new option to pass a custom logging function to the client.
If no logger specified the client will write log messages to console, default logging level is info.

Add 'copyBuffer' option

This release introduces a new option called 'copyBuffer', the option is not set by default.
If the option is set the client will create a new buffer for each flush() call with the data belongs to the returned promise.
This prevents creating duplicate rows if await is missed when calling flush() or if the calls to flush() are not serialised.

Example:

const sender = new Sender({ copyBuffer: true });
