HTML_Entities dependency doesn't work with PackageCompiler

Hi, I hope you are doing great

Thank you for your effort in this package

Just to report that the dependency [HTML_Entities](https://github.com/JuliaString/HTML_Entities.jl) avoid this package to work with [PackageCompiler](https://github.com/JuliaString/HTML_Entities.jl/issues/17)

This issue was fixed in this [PR](https://github.com/JuliaString/HTML_Entities.jl/pull/15) but the release hasn't been done. [I tried to do the release by myself](https://github.com/JuliaString/HTML_Entities.jl/pull/18) but I cannot because I don't belong to JuliaString org.

I hope someone of you can help us with the release,

Thank you!
