v0.3.0 Release - Change import syntax

• Added HISTORY.md file
• Changed import syntax to from pandas_path import path to better support custom accessors. This means that we do not register .path unless you import .path so that in other libraries you don't have to add the .path accessor if you are just registering your own custom accessor.
• Added quickstart section to README
• Fix bug where we tried to instantiate with blank string for an example rather than first item in the Series

v0.2.0 release

• Enable custom path accessors for other objects that implement pathlib methods
• Update limitations with Path on LHS in older Python failing.
• Add additional tests with Path objects on LHS and RHS
• Migrate to github actions for tests
• Add code coverage
• Minor updates to README (missing link, badges)
