Enhancements and Bug Fixes

Tables Feature
- Added the `create_table` method, which returns a `Table` object. This can be used to display watchlists, order windows, position windows and more.
- See the new page on the docs for more information!

Bugs
- Fixed a bug preventing the named column of a line to not work as a label of the series.
- Fixed a bug causing drawings loaded from the minute timeframe to not show on a daily timeframe.
- Fixed a bug causing `chart.exit` to not work.
- Fixed a bug preventing the chart from being moved after placing a ray.
- Fixed the ‘price in hoveringOver’ web console error.

Enhancements
- The date/time column can also be the `name` of the passed series object.
- Added the `label` method to `HorizontalLine`, allowing for the price line label of horizontal lines to be updated.
- `None` or an empty DataFrame can now be passed to `line.set` as a means to clear it.
- Seperate Chart objects will now run on the same pywebview instance. This means that any Chart objects created after the first will inherit the first Chart’s API.
- Reorganized the documentation for clarity.
