Feature Request: Put equation number on the right instead of left

[siddjain]

Per this thread:
asciidoctor/asciidoctor#3518

When asciidoctor-mathematical is used with asciidoctor-pdf to generate a PDF the equation number appears to the left. This is a request to add a flag that would allow the author to generate a PDF with equation numbers on the right which is the expected norm.

I just ran a test with the asciidoctor docker (https://github.com/asciidoctor/docker-asciidoctor) and the equation number appeared on the right. It wasn't flush right, but it was to the right of the equation.
