Release to rubygems to support BigDecimal 4.x?

[owst]

Hi,

Thanks for your work in ad8367a - could you release a new version to rubygems so that we can take advantage of that commit while using bigdecimal-4.0.1?

Thanks!
Owen.

I want to fix font subsetting first. I promise, it won't take years.

Hi @pointlessone @owst !
would be really good to have this released please! :)

Thanks @owst for opening the pr!

@pointlessone would it be reasonable to consider releasing now for BigDecimal 4, and then release again when you have font subsetting?
