{leaf.magic} - Use Modern Icon Libraries in Leaflet Markers

The goal of {leaf.magic} is to overcome the somewhat outdated "Font Awesome" implementation in vanilla R {leaflet} by constructing markers on the fly using {fontawesome} or {bsicons} and {magick}. There are three issues {leaf.magic} sets out to overcome:

• leaflet::awesomeIcons() is limited to Font Awesome 4 👎

• leaflet::awesomeIcons() is limited to a handful of discrete colours 👎

• leaflet::awesomeIcons() is limited to a single marker size 👎

• Vanilla {leaflet} doesn't provide any additional features to construct legends, icon palettes, or such like 👎

{leaf.magic} attempts to solve all of this:

• magicIcons() uses up-to-date versions of Font Awesome, Bootstrap, and Ionicons Icons, powered by {fontawesome} and {bsicons} ✅

• magicIcons() uses {fontawesome} to grab a marker shape, and can therefore colour and resize it however the user desires ✅

• {leaf.magic} exports functions like iconBin() and addIconLegend() to help developers communicate the meanings of icons to users ✅

{leaf.magic} is thoroughly documented on the package website, which includes a getting started guide.

Installation
