Bumped echarts JavaScript library to `4.6.0`, [PR #121](https://github.com/JohnCoene/echarts4r/pull/121), also bumped echarts gl to `1.2.1`.

Every function that adds a serie to chart (e.g.: `e_bar`) have been turned into methods that now can be applied to proxies (`echarts4rProxy`), see the [development vignette](https://echarts4r.john-coene.com/articles/proxies.html) for more. This implies some minute changes to the `echarts4rProxy`: nothing broken though.

- `e_scatter_3d` correctly takes `bind` argument when `coords` is set to `cartesian3D` (previously incorrect).
- Bumped number of built-in themes to 40+.
- Added `e_remove_serie_p` to remove series from the graph.
- Added `e_axis_labels` to easily place axis labels.

- Fixed a few issues with `e_mark*` family, labels and multiple marks correctly work.

- `e_visual_map` drops `NA`s.
- Added `e_axis_stagger` function to stagger x axis labels.

# echarts4r 0.2.3

- Tooltip formatters correctly identify locale on UNIX systems, thanks to [Artem](https://github.com/artemklevtsov).
- `e_mark_point()`, `e_mark_line()` and `e_mark_area()` no longer use `grep()`, which means the serie will only be matched with the exact same name. Thanks @shrektan for the reporting and PR (#80, #81).
- Multiple `e_title` now allowed.
- Multiple `e_visual_map` in [timelines](https://echarts4r.john-coene.com/articles/timeline.html) is now fixed.

- `e_charts` family forces data.frame conversion to avoid jsonlite bug.
- Fixed bug in the `formatter` argument of `e_tooltip` where passing custom function was not working.
