Compat problems

[baggepinnen]

Plotly.jl does not have upper bounds listed on some of it's dependencies, notably HTTP.jl. Upper bounds have been introduced on all dependencies in general, c.f., https://github.com/JuliaRegistries/General/blob/master/P/Plotly/Compat.toml#L2
This causes some confusion when the package manager throws compatibility errors, e.g.,

(@v1.6) pkg> add ECharts#master
     Cloning git-repo `https://github.com/randyzwitch/ECharts.jl.git`
    Updating git-repo `https://github.com/randyzwitch/ECharts.jl.git`

There is a conflict for HTTP but there is on reason listed.

It would be great if a new release of this package was made that lists proper compat bounds, including compat with the latest version of HTTP.
