2.1.0

A lot of internal changes, nothing to outwards facing.

One breaking change:

• No longer exporting or using flattenSegments(), instead, just write this yourself. There's no need for it to be a permanent part of the library. This can easily be replaced with the following:

const data = getData({ path, segments, samples, precision });
const flattenedData = data.flatMap(({ samples }) => samples);  // boom.

• A bunch of cleanups, more documentation, and elmination of flattenSegments c33e9b8
• Closing the path properly now 763db67
• Object config for sample and segment 014ab36
• Documentation change 486a4bd
