Coordinate-canvas

This PR features minor quality changes regarding workflow and outdated documentation updates.

What's Changed
* Update package information and integration workflows by erlete in https://github.com/erlete/coordinate-canvas/pull/4

**Full Changelog**: https://github.com/erlete/coordinate-canvas/compare/v1.4.0...v1.4.1

This PR features a revolutionary functionality for the repository: multiple line handling on the same plot. The user is allowed to switch between lines directly using the number keys.

As it was mentioned in https://github.com/erlete/coordinate-canvas/pull/1, the spline generation issue caused by consecutive identical coordinates was successfully solved.

Furthermore, an input handling module was added in order to properly request and verify the required input format for the package to work.

What's Changed
* Multi-line direct support, input handling and error solving by erlete in https://github.com/erlete/coordinate-canvas/pull/2

**Full Changelog**: https://github.com/erlete/coordinate-canvas/compare/v1.3.1...v1.4.0

Solved an issue that caused the spline generation to throw an error and cause unexpected behavior from the canvas when two identical coordinates were consecutively drawn.

Also renamed modules, updated requirements and documented code.

**Full Changelog**: https://github.com/erlete/coordinate-canvas/compare/v1.3.0...v1.3.1

This release features a new coordinate visualization method: a visual spline. This allows the user to better predict how the curvature and yaw of the line they are drawing would look like when cubically interpolated.

The spline is only visual. Saved data is still the same: the individually drawn points.

**Full Changelog**: https://github.com/erlete/coordinate-canvas/compare/v1.2.0...v1.3.0

Fixed an error that appeared when the module was executed via `python3 -m coordinate-canvas` since the module itself did not have a `__main__.py` file and could not be directly executed.

Quick fix for the PyPI package release.
