Refactoring and fixing Line graph

Child of #1020
As a user I want the functionality to have line graph in Tempus, so that I can analyse well log data using charts and various widgets.

What needs to be done:
Line graph component is not working as expected. We need to revisit the associated js and find the core issues, fix and refactor as needed.

Scope:
1. Line graph should be plotted based on the data points in well log data.
2. The line graph should be depth based so that the visualization for the user is natural. Configurable (Line width and color)
3. Ability to plot multiple Line graph in a single Track.
4. Area fill in the track based on the line graph plotted either left or right, which should be configurable. (Color, fill alignment)
5. The line color and fill color should both be configurable and a user can choose 2 separate colors for line and area fill.
