Use URL parameters to set draw configuration settings

[zeo210]

As a way for players to quickly load up configured card draw without having to manually map a ruleset to the configurations in the tool, utilize URL parameters that set different parts of the draw configuration to their indicated value. (ex https://ddr.tools?draw=7&lvl_min=10&lvl_max=19&...)

I think #267 and #268 both help address the same issues, but this is also a good solution that might be worth having at the same time. (It's something I've even had in mind for years, but never really spent any time on)
